Defines a global method with the specified name, attributes, return type, and parameter types.

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

public MethodBuilder DefineGlobalMethod(
	string name,
	MethodAttributes attributes,
	Type returnType,
	Type[] parameterTypes
)

Parameters

name
Type: System.String

The name of the method. name cannot contain embedded nulls.

attributes
Type: System.Reflection.MethodAttributes

The attributes of the method. attributes must include Static.

returnType
Type: System.Type

The return type of the method.

parameterTypes
Type: System.Type[]

The types of the method's parameters.

Return Value

Type: System.Reflection.Emit.MethodBuilder

The defined global method.

Exception Condition
ArgumentException

The method is not static. That is, attributes does not include Static.

-or-

The length of name is zero

-or-

An element in the Type array is null.

ArgumentNullException

name is null.

InvalidOperationException

CreateGlobalFunctions has been previously called.

The global method that this method defines is not usable until you call CreateGlobalFunctions.

System_CAPS_noteNote

Starting with the .NET Framework 2.0 Service Pack 1, this member no longer requires ReflectionPermission with the ReflectionPermissionFlag.ReflectionEmit flag. (See Security Issues in Reflection Emit.) To use this functionality, your application should target the .NET Framework 3.5 or later.

The following example illustrates the use of DefineGlobalMethod to create a type-independent method tied to the current ModuleBuilder. After building the global method, CreateGlobalFunctions must be called in order to complete it.

AppDomain currentDomain;
AssemblyName myAssemblyName;
MethodBuilder myMethodBuilder=null;
ILGenerator myILGenerator;

// Get the current application domain for the current thread.
currentDomain = AppDomain.CurrentDomain;
myAssemblyName = new AssemblyName();
myAssemblyName.Name = "TempAssembly";

// Define a dynamic assembly in the 'currentDomain'.
myAssemblyBuilder = 
   currentDomain.DefineDynamicAssembly
               (myAssemblyName, AssemblyBuilderAccess.RunAndSave);
// Define a dynamic module in "TempAssembly" assembly.
myModuleBuilder = myAssemblyBuilder.DefineDynamicModule("TempModule");

// Define a global method in the 'TempModule' module.
myMethodBuilder = myModuleBuilder.DefineGlobalMethod
     ("MyMethod1",MethodAttributes.Static|MethodAttributes.Public,
           null,null);
myILGenerator = myMethodBuilder.GetILGenerator();
myILGenerator.EmitWriteLine("Hello World from global method.");
myILGenerator.Emit(OpCodes.Ret);
// Fix up the 'TempModule' module .
myModuleBuilder.CreateGlobalFunctions();
