ConstructorBuilder.SetSymCustomAttribute Method

Sets this constructor's custom attribute associated with symbolic information.

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

public void SetSymCustomAttribute(
	string name,
	byte[] data


Type: System.String
The name of the custom attribute.
Type: System.Byte[]
The value of the custom attribute.


The containing type has been created using CreateType.


The module does not have a symbol writer defined. For example, the module is not a debug module.

The following code sample illustrates the use of SetSymCustomAttributes.

MethodBuilder myMethodBuilder = null;
AppDomain myCurrentDomain = AppDomain.CurrentDomain;
// Create assembly in current CurrentDomain.
AssemblyName myAssemblyName = new AssemblyName();
myAssemblyName.Name = "TempAssembly";
// Create a dynamic assembly.
myAssemblyBuilder = myCurrentDomain.DefineDynamicAssembly
         (myAssemblyName, AssemblyBuilderAccess.Run);
// Create a dynamic module in the assembly.
myModuleBuilder = myAssemblyBuilder.DefineDynamicModule("TempModule",true);
FieldInfo myFieldInfo =
   myModuleBuilder.DefineUninitializedData("myField", 2, FieldAttributes.Public);
// Create a type in the module.
TypeBuilder myTypeBuilder = myModuleBuilder.DefineType("TempClass",TypeAttributes.Public);
FieldBuilder myGreetingField = myTypeBuilder.DefineField("Greeting", 
                                    typeof(String), FieldAttributes.Public);
Type[] myConstructorArgs = { typeof(String) };
// Define a constructor of the dynamic class.
ConstructorBuilder myConstructor = myTypeBuilder.DefineConstructor(
MethodAttributes.Public, CallingConventions.Standard, myConstructorArgs);
// Display the name of the constructor.
Console.WriteLine("The constructor name is  : "+ myConstructor.Name);
myConstructor.SetSymCustomAttribute("MySimAttribute", new byte[]{01,00,00});
