ilspycmd: 11.2.0.0
ICSharpCode.Decompiler: 11.2.0.0
dotnet tool for decompiling .NET assemblies and generating portable PDBs
Usage: ilspycmd [options] <Assembly file name(s)>
Arguments:
Assembly file name(s) The list of assemblies that is being
decompiled. This argument is
mandatory.
Options:
-v|--version Show version of ICSharpCode.Decompiler
used.
-h|--help Show help information.
-o|--outputdir <directory> The output directory, if omitted
decompiler output is written to
standard out.
-p|--project Decompile assembly as compilable
project. This requires the output
directory option.
-t|--type <type-name> The fully qualified name of the type
to decompile.
-m|--member <doc-id-or-token> The single member to decompile: an XML
documentation id string (e.g.
"M:System.String.Concat(System.String,System.String)",
as also accepted by the UI's
--navigateto option) or a metadata
token (e.g. 0x06000005).
-il|--ilcode Show IL code.
--il-sequence-points Show IL with sequence points. Implies
-il.
-genpdb|--generate-pdb Generate PDB.
-usepdb|--use-varnames-from-pdb Use variable names from PDB.
-l|--list <entity-type(s)> Lists all entities of the specified
type(s). Valid types: c(lass),
i(nterface), s(truct), d(elegate),
e(num)
--list-resources Lists all embedded resources in the
assembly. Entries inside .resources
containers are listed individually as
'<container>/<entry>'.
--resource <name> Extract a single resource by name (as
printed by --list-resources).
Resources whose name ends with '.baml'
are decompiled to XAML.
--decompile-baml Deprecated: -p decompiles BAML
resources to XAML files (Page items)
on its own. Accepted so that existing
scripts keep working.
--dump-table <table> Dump a metadata table: prints RID,
token, names, heap offsets and coded
indexes of every row. <table> is the
ECMA-335 table name (e.g. TypeDef,
Property, MethodSemantics;
case-insensitive) or table number
(decimal or 0x-prefixed hex, e.g.
0x17).
--dump-pdb Dump the debug information of the
assembly's PDB: documents, per-method
sequence points, the scope tree with
its variables, constants and imports,
and custom debug information. Reads
both Portable and Windows PDBs. Use
-usepdb:<file> to point at a PDB that
is not next to the assembly.
--json Output as JSON. Only supported
together with --dump-table or
--dump-pdb.
-lv|--languageversion <version> C# Language version: CSharp1, CSharp2,
CSharp3, CSharp4, CSharp5, CSharp6,
CSharp7, CSharp7_1, CSharp7_2,
CSharp7_3, CSharp8_0, CSharp9_0,
CSharp10_0, CSharp11_0, CSharp12_0,
CSharp13_0, Preview or Latest
Allowed values are: CSharp1, CSharp2,
CSharp3, CSharp4, CSharp5, CSharp6,
CSharp7, CSharp7_1, CSharp7_2,
CSharp7_3, CSharp8_0, CSharp9_0,
CSharp10_0, CSharp11_0, CSharp12_0,
CSharp13_0, CSharp14_0, CSharp15_0,
Preview, Latest.
Default value is: Latest.
--ilspy-settingsfile <path> Path to an ILSpy settings file.
-ds|--decompiler-setting <value> Set a decompiler setting. Use multiple
times to set multiple settings.
-r|--referencepath <path> Path to a directory containing
dependencies of the assembly that is
being decompiled.
--ignore-decompilation-errors Exit with success even when parts of
the assembly could not be decompiled.
The affected code carries the error
text in the output and the failures
are listed on stderr either way; only
the exit status changes.
--no-dead-code Remove dead code.
--no-dead-stores Remove dead stores.
-d|--dump-package Dump package assemblies into a folder.
This requires the output directory
option.
--bundle-entry <name> The assembly inside a single-file
bundle (or other package) to work on,
as printed when such a file is passed
without this option. Ignored for input
files that are not packages.
--nested-directories Use nested directories for namespaces.
--disable-updatecheck If using ilspycmd in a tight loop or
fully automated scenario, you might
want to disable the automatic update
check.
--generate-diagrammer Generates an interactive HTML
diagrammer app from selected types in
the target assembly - to the
--outputdir or in a 'diagrammer'
folder next to to the assembly by
default.
--generate-diagrammer-include An optional regular expression
matching Type.FullName used to
whitelist types to include in the
generated diagrammer.
--generate-diagrammer-exclude An optional regular expression
matching Type.FullName used to
blacklist types to exclude from the
generated diagrammer.
--generate-diagrammer-report-excluded Outputs a report of types excluded
from the generated diagrammer -
whether by default because
compiler-generated, explicitly by
'--generate-diagrammer-exclude' or
implicitly by
'--generate-diagrammer-include'. You
may find this useful to develop and
debug your regular expressions.
--generate-diagrammer-docs The path or file:// URI of the XML
file containing the target assembly's
documentation comments. You only need
to set this if a) you want your
diagrams annotated with them and b)
the file name differs from that of the
assembly. To enable XML documentation
output for your assembly, see
https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/xmldoc/#create-xml-documentation-output
--generate-diagrammer-strip-namespaces Optional space-separated namespace
names that are removed for brevity
from XML documentation comments. Note
that the order matters: e.g. replace
'System.Collections' before 'System'
to remove both of them completely.
Remarks:
-o is valid with every option and required when using -p or -d.
Examples:
Decompile assembly to console out.
ilspycmd sample.dll
Decompile assembly to destination directory (single C# file).
ilspycmd -o c:\decompiled sample.dll
Decompile assembly to destination directory, create a project file, one source file per type.
ilspycmd -p -o c:\decompiled sample.dll
Decompile assembly to destination directory, create a project file, one source file per type,
into nicely nested directories.
ilspycmd --nested-directories -p -o c:\decompiled sample.dll
Generate a HTML diagrammer containing all type info into a folder next to the input assembly
ilspycmd sample.dll --generate-diagrammer
Generate a HTML diagrammer containing filtered type info into a custom output folder
(including types in the LightJson namespace while excluding types in nested LightJson.Serialization namespace)
ilspycmd sample.dll --generate-diagrammer -o c:\diagrammer --generate-diagrammer-include LightJson\\..+ --generate-diagrammer-exclude LightJson\\.Serialization\\..+
List all embedded resources in a WPF assembly (including BAML entries inside .g.resources containers).
ilspycmd sample.dll --list-resources
Extract a single resource. If the name ends with .baml, the output is decompiled XAML; otherwise raw bytes.
ilspycmd sample.dll --resource sample.g.resources/mainwindow.baml -o c:\decompiled
Decompile assembly as a compilable project. BAML resources become XAML Page items.
ilspycmd sample.dll -p -o c:\decompiled
