Encodes method signature blob.
public System.Reflection.Metadata.Ecma335.MethodSignatureEncoder MethodSignature (System.Reflection.Metadata.SignatureCallingConvention convention = System.Reflection.Metadata.SignatureCallingConvention.Default, int genericParameterCount = 0, bool isInstanceMethod = false);
member this.MethodSignature : System.Reflection.Metadata.SignatureCallingConvention * int * bool -> System.Reflection.Metadata.Ecma335.MethodSignatureEncoder
Public Function MethodSignature (Optional convention As SignatureCallingConvention = System.Reflection.Metadata.SignatureCallingConvention.Default, Optional genericParameterCount As Integer = 0, Optional isInstanceMethod As Boolean = false) As MethodSignatureEncoder
Parameters
- convention
- SignatureCallingConvention
Calling convention.
- genericParameterCount
- Int32
Number of generic parameters.
- isInstanceMethod
- Boolean
true
to encode an instance method signature, false
to encode a static method signature.
Returns
An encoder of the rest of the signature including return value and parameters.
Exceptions
genericParameterCount
is not in range [0, 0xffff].
Examples
This example shows how to encode different method signatures:
static BlobBuilder EncodeMethodSignatureParameterless()
{
// void Method()
var methodSignature = new BlobBuilder();
new BlobEncoder(methodSignature).
MethodSignature().
Parameters(0, returnType => returnType.Void(), parameters => { });
return methodSignature;
}
static BlobBuilder EncodeMethodSignaturePrimitiveTypes()
{
// double Method(double x, double y)
var methodSignature = new BlobBuilder();
new BlobEncoder(methodSignature).
MethodSignature().
Parameters(2, returnType => returnType.Type().Double(),
parameters => {
parameters.AddParameter().Type().Double();
parameters.AddParameter().Type().Double();
});
return methodSignature;
}
static BlobBuilder EncodeMethodSignatureClassType(MetadataBuilder metadataBuilder)
{
// void Method(System.Threading.Thread x)
var methodSignature = new BlobBuilder();
AssemblyReferenceHandle mscorlibAssemblyRef = metadataBuilder.AddAssemblyReference(
name: metadataBuilder.GetOrAddString("System.Threading.Thread"),
version: new Version(4, 0, 0, 0),
culture: default(StringHandle),
publicKeyOrToken: default(BlobHandle),
flags: default(AssemblyFlags),
hashValue: default(BlobHandle));
TypeReferenceHandle typeRef = metadataBuilder.AddTypeReference(
mscorlibAssemblyRef,
metadataBuilder.GetOrAddString("System.Threading"),
metadataBuilder.GetOrAddString("Thread"));
new BlobEncoder(methodSignature).
MethodSignature().
Parameters(1, returnType => returnType.Void(),
parameters => {
parameters.AddParameter().Type().Type(typeRef, false);
});
return methodSignature;
}
static BlobBuilder EncodeMethodSignatureModifiedTypes()
{
// void Method(ref int x, int[] y)
var methodSignature = new BlobBuilder();
new BlobEncoder(methodSignature).
MethodSignature().
Parameters(2, returnType => returnType.Void(),
parameters => {
parameters.AddParameter().Type(isByRef: true).Int32();
parameters.AddParameter().Type().SZArray().Int32();
});
return methodSignature;
}
public static BlobBuilder EncodeMethodSignatureGeneric()
{
// void Method<T>(T x)
var methodSignature = new BlobBuilder();
new BlobEncoder(methodSignature).
MethodSignature(genericParameterCount: 1).
Parameters(1, returnType => returnType.Void(),
parameters => {
parameters.AddParameter().Type().GenericMethodTypeParameter(0);
});
return methodSignature;
}
Remarks
Method signature blobs are used when defining or referencing methods in .NET metadata. For a complete example of emitting a method definition, see the MetadataBuilder class remarks.
