DynamicILInfo.SetCode Method (Byte*, Int32, Int32)

Sets the code body of the associated dynamic method.

This API is not CLS-compliant. The CLS-compliant alternative is SetCode(Byte[], Int32).

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

public void SetCode(
	byte* code,
	int codeSize,
	int maxStackSize


Type: System.Byte*
A pointer to a byte array containing the MSIL stream.
Type: System.Int32
The number of bytes in the MSIL stream.
Type: System.Int32
The maximum number of items on the operand stack when the method is executing.


code is null and codeSize is greater than 0.


codeSize is less than 0.

No validity checks are performed on the MSIL stream.

Calling this method a second time replaces the first MSIL stream with the second.

Generating your own metadata and MSIL requires familiarity with the Common Language Infrastructure (CLI) documentation, especially "Partition II: Metadata Definition and Semantics" and "Partition III: CIL Instruction Set." 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.
