Type.GetMethod Method (String, BindingFlags)

Searches for the specified method, using the specified binding constraints.

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

public MethodInfo GetMethod (
	string name,
	BindingFlags bindingAttr
)
public final MethodInfo GetMethod (
	String name, 
	BindingFlags bindingAttr
)
public final function GetMethod (
	name : String, 
	bindingAttr : BindingFlags
) : MethodInfo

Parameters

name

The String containing the name of the method to get.

bindingAttr

A bitmask comprised of one or more BindingFlags that specify how the search is conducted.

-or-

Zero, to return a null reference (Nothing in Visual Basic).

Return Value

A MethodInfo object representing the method that matches the specified requirements, if found; otherwise, a null reference (Nothing in Visual Basic).

Exception typeCondition

AmbiguousMatchException

More than one method is found with the specified name and matching the specified binding constraints.

ArgumentNullException

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

The following BindingFlags filter flags can be used to define which methods to include in the search:

  • You must specify either BindingFlags.Instance or BindingFlags.Static in order to get a return.

  • Specify BindingFlags.Public to include public methods in the search.

  • Specify BindingFlags.NonPublic to include non-public methods (that is, private and protected members) in the search.

  • Specify BindingFlags.FlattenHierarchy to include public and protected static members up the hierarchy; private static members in inherited classes are not included.

The following BindingFlags modifier flags can be used to change how the search works:

  • BindingFlags.IgnoreCase to ignore the case of name.

  • BindingFlags.DeclaredOnly to search only the methods declared on the Type, not methods that were simply inherited.

See System.Reflection.BindingFlags for more information.

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).

NoteNote

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.

NoteNote

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 method that matches the specified binding flags and displays its signature.


using System;
using System.Reflection;

class MyClass
{
    public void MyMethod()
    {    
    }
}

public class Type_GetMethod
{
    public static void Main()
    {
        try
        {
            // Get the type of MyClass.
            Type myType = typeof(MyClass);
         
            // Get the method information for MyClass.
            MethodInfo myMethodInfo = myType.GetMethod("MyMethod",
                BindingFlags.Public|BindingFlags.Instance );
         
            // Display the method information.
            Console.WriteLine("\nThe signature of MyMethod is: {0}", myMethodInfo.ToString());
        }
        catch(Exception e)
        {
            Console.WriteLine("Exception: {0}", e.Message);
        }
    }
}

            MethodInfo myMethodInfo = myType.GetMethod("MyMethod",

            Console.WriteLine("\nThe signature of MyMethod is: {0}",
                myMethodInfo.ToString());
        }

        }
