DynamicILInfo.SetLocalSignature Method (Byte*, Int32)

Sets the local variable signature that describes the layout of local variables for the associated dynamic method.

This API is not CLS-compliant. The CLS-compliant alternative is SetLocalSignature(Byte[]).

Namespace:  System.Reflection.Emit
Assembly:  mscorlib (in mscorlib.dll)

public void SetLocalSignature(
	byte* localSignature,
	int signatureSize


Type: System.Byte*
An array that contains the layout of local variables for the associated DynamicMethod.
Type: System.Int32
The number of bytes in the signature.


localSignature is null and signatureSize is greater than 0.


signatureSize is less than 0.

The local variable signature describes the layout of a method's local variables. To simplify construction of the local variable signature, use the static (Shared in Visual Basic) SignatureHelper.GetLocalVarSigHelper method to get a SignatureHelper for the local signature.

For information on local variable signatures, see the Common Language Infrastructure (CLI) documentation, especially "Partition II: Metadata Definition and Semantics". The documentation is available online; see ECMA C# and Common Language Infrastructure Standards on MSDN and Standard ECMA-335 - Common Language Infrastructure (CLI) on the Ecma International Web site.
