MethodBuilder is used to fully describe a method in Microsoft intermediate language (MSIL), including the name, attributes, signature, and method body. It is used in conjunction with the TypeBuilder class to create classes at runtime.

NoteNote

The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: MayLeakOnAbort. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.

An example using the MethodBuilder class to create a method within a dynamic type is provided below.

No code example is currently available or this language may not be supported.

.NET Framework

Supported in: 4.6, 4.5, 4, 3.5, 3.0, 2.0, 1.1
