Delegate.CreateDelegate Method (Type, Object, String, Boolean)
Assembly: mscorlib (in mscorlib.dll)
public static Delegate CreateDelegate ( Type type, Object target, string method, bool ignoreCase )
public static Delegate CreateDelegate ( Type type, Object target, String method, boolean ignoreCase )
public static function CreateDelegate ( type : Type, target : Object, method : String, ignoreCase : boolean ) : Delegate
Not applicable.
Parameters
- type
The Type of delegate to create.
- target
The class instance on which method is invoked.
- method
The name of the instance method that the delegate is to represent.
- ignoreCase
A Boolean indicating whether to ignore the case when comparing the name of the method.
Return Value
A delegate of the specified type that represents the specified instance method to invoke on the specified class instance.| Exception type | Condition |
|---|---|
| type is a null reference (Nothing in Visual Basic). -or- target is a null reference (Nothing in Visual Basic). -or- method is a null reference (Nothing in Visual Basic). | |
| type does not inherit MulticastDelegate. -or- type is not a RuntimeType. See Runtime Types in Reflection. -or- method is not an instance method. -or- method cannot be bound, for example because it cannot be found. | |
| The Invoke method of type is not found. | |
| The caller does not have the permissions necessary to access method. |
This method creates delegates for instance methods only. An instance method is a method that is associated with an instance of a class; a static method is a method that is associated with the class itself.
This method overload is equivalent to calling the CreateDelegate(Type,Object,String,Boolean,Boolean) method overload, specifying true for throwOnBindFailure.

| Starting with the , this method can be used to access non-public methods if the caller has been granted ReflectionPermission with the ReflectionPermissionFlag.ReflectionEmit flag and if the grant set of the non-public methods is restricted to the caller’s grant set, or a subset thereof. (See Security Considerations for Reflection.) To use this functionality, your application should target the . For more information, see The .NET Framework 3.5 Architecture. |
- ReflectionPermission for accessing a non-public method when the grant set of the non-public method is restricted to the caller's grant set, or a subset thereof. Associated enumeration: System.Security.Permissions.ReflectionPermissionFlag.RestrictedMemberAccess
- ReflectionPermission for accessing a non-public method regardless of its grant set. Associated enumeration: ReflectionPermissionFlag.MemberAccess
- ReflectionPermission when invoked late-bound through mechanisms such as Type.InvokeMember. Associated enumeration: ReflectionPermissionFlag.MemberAccess.
