Type.GetMethod Method (String)

Searches for the public method with the specified name.

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

Public Function GetMethod ( _
	name As String _
) As MethodInfo
Dim instance As Type
Dim name As String
Dim returnValue As MethodInfo

returnValue = instance.GetMethod(name)
public final MethodInfo GetMethod (
	String name
public final function GetMethod (
	name : String
) : MethodInfo



The String containing the name of the public method to get.

Return Value

A MethodInfo object representing the public method with the specified name, if found; otherwise, a null reference (Nothing in Visual Basic).

Exception typeCondition


More than one method is found with the specified name.


name is a null reference (Nothing in Visual Basic).

The search for name is case-sensitive. The search includes public static and public instance methods.

If the requested type is non-public and the caller does not have ReflectionPermission to reflect non-public objects outside the current assembly, this method returns a null reference (Nothing in Visual Basic).


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 GetMember("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.

The following example gets the parameters of MyFunction in MyClass and displays their position and data type.
