Type.GetMethod Method (String, Type, ParameterModifier)
Searches for the specified public method whose parameters match the specified argument types and modifiers.
Assembly: mscorlib (in mscorlib.dll)
An array of Type objects representing the number, order, and type of the parameters for the method to get.
An empty array of Type objects (as provided by the EmptyTypes field) to get a method that takes no parameters.
An array of ParameterModifier objects representing the attributes associated with the corresponding element in the types array. To be only used when calling through COM interop, and only parameters that are passed by reference are handled. The default binder does not process this parameter.
Although the default binder does not process ParameterModifier (the modifiers parameter), you can use the abstract System.Reflection.Binder class to write a custom binder that does process modifiers. ParameterModifier is only used when calling through COM interop, and only parameters that are passed by reference are handled.
The types array and the modifiers array have the same length. A parameter specified in the types array can have the following attributes, which are specified in the modifiers array: pdIn, pdOut, pdLcid, pdRetval, pdOptional, and pdHasDefault, which represent [In], [Out], [lcid], [retval], [optional], and a value specifying whether the parameter has a default value. A parameter's associated attributes are stored in the metadata and are used for interoperability.
The search for name is case-sensitive. The search includes public static and public instance methods.
You cannot omit parameters when looking up constructors and methods. You can only omit parameters when invoking.
If the current T:System.Type represents a constructed generic type, this method returns the MethodInfo with the type parameters replaced by the appropriate type arguments.
If the current Type represents a type parameter in the definition of a generic type or generic method, this method searches the methods of the class constraint, or the methods of Object if there is no class constraint.
For generic methods, do not include the type arguments in name. For example, the C# code GetMethod("MyMethod<int>") searches for a member with the text name "MyMethod<int>", rather than for a method named MyMethod that has one generic argument of type int. Instead, use GetMethod("MyMethod") with the appropriate parameter in the types array.
