Type.GetMethod Method (String, BindingFlags)

Microsoft Silverlight will reach end of support after October 2021. Learn more.

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

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

Syntax

'Declaration
Public Function GetMethod ( _
    name As String, _
    bindingAttr As BindingFlags _
) As MethodInfo

public MethodInfo GetMethod(
    string name,
    BindingFlags bindingAttr
)

Parameters

Return Value

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

Implements

IReflect.GetMethod(String, BindingFlags)

Exceptions

Exception Condition
AmbiguousMatchException

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

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

Remarks

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 methods) 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.

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.

Examples

The following example gets the method that matches the specified binding flags.

NoteNote:

To run this example, see Building Examples That Use a Demo Method and a TextBlock Control.

 

Imports System.Reflection

Class Example

   ' Method to get:
   Public Sub MethodA()
   End Sub


   Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)

      ' Get MethodA()
      Dim mInfo As MethodInfo = GetType(Example).GetMethod("MethodA", _
       BindingFlags.Public Or BindingFlags.Instance)
      outputBlock.Text += String.Format("Found method: {0}", mInfo) & vbCrLf

   End Sub
End Class


using System;
using System.Reflection;

class Example
{

   // Method to get:
   public void MethodA() { }


   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {

      // Get MethodA()
      MethodInfo mInfo = typeof(Example).GetMethod("MethodA",
          BindingFlags.Public | BindingFlags.Instance);
      outputBlock.Text += String.Format("Found method: {0}", mInfo) + "\n";

   }
}
