For a detailed description of the member opcodes, see the Common Language Infrastructure (CLI) documentation, especially "Partition III: CIL Instruction Set" and "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.

The following example demonstrates the construction of a dynamic method using ILGenerator to emit OpCodes into a MethodBuilder.
