DynamicMethod.GetILGenerator Method (Int32)

Returns a Microsoft intermediate language (MSIL) generator for the method with the specified MSIL stream size.

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

public ILGenerator GetILGenerator (
	int streamSize
)
public ILGenerator GetILGenerator (
	int streamSize
)
public function GetILGenerator (
	streamSize : int
) : ILGenerator
Not applicable.

Parameters

streamSize

The size of the MSIL stream, in bytes.

Return Value

An ILGenerator object for the method, with the specified MSIL stream size.

After a dynamic method has been completed, by calling the CreateDelegate or Invoke method, any further attempt to add MSIL is ignored. No exception is thrown.

The following code example demonstrates this method overload. This code example is part of a larger example provided for the DynamicMethod class.

// Create an array that specifies the parameter types of the
// overload of Console.WriteLine to be used in Hello.
Type[] writeStringArgs = {typeof(string)};
// Get the overload of Console.WriteLine that has one
// String parameter.
MethodInfo writeString = typeof(Console).GetMethod("WriteLine", 
    writeStringArgs);

// Get an ILGenerator and emit a body for the dynamic method,
// using a stream size larger than the IL that will be
// emitted.
ILGenerator il = hello.GetILGenerator(256);
// Load the first argument, which is a string, onto the stack.
il.Emit(OpCodes.Ldarg_0);
// Call the overload of Console.WriteLine that prints a string.
il.EmitCall(OpCodes.Call, writeString, null);
// The Hello method returns the value of the second argument;
// to do this, load the onto the stack and return.
il.Emit(OpCodes.Ldarg_1);
il.Emit(OpCodes.Ret);
