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

public:
 void SetSymCustomAttribute(System::String ^ name, cli::array <System::Byte> ^ data);

public void SetSymCustomAttribute (string name, byte[] data);

member this.SetSymCustomAttribute : string * byte[] -> unit

Public Sub SetSymCustomAttribute (name As String, data As Byte())

Parameters

name: String

The name of the custom attribute.

data: Byte[]

The value of the custom attribute.

Exceptions

InvalidOperationException

The containing type has been created using CreateType().

-or-

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

Remarks

The following code sample illustrates the use of SetSymCustomAttributes.

MethodBuilder^ myMethodBuilder = nullptr;
AppDomain^ myCurrentDomain = AppDomain::CurrentDomain;
// Create assembly in current CurrentDomain.
AssemblyName^ myAssemblyName = gcnew 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",
   String::typeid, FieldAttributes::Public );
array<Type^>^ myConstructorArgs = {String::typeid};
// 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  : {0}", myConstructor->Name );
array<Byte>^ temp0 = {01,00,00};
myConstructor->SetSymCustomAttribute( "MySimAttribute", temp0 );

         (myAssemblyName, AssemblyBuilderAccess.Run);
// Create a dynamic module in the assembly.

// Define a constructor of the dynamic class.
ConstructorBuilder myConstructor = myTypeBuilder.DefineConstructor(
MethodAttributes.Public, CallingConventions.Standard, myConstructorArgs);
// Display the name of the constructor.
