Type.GetTypeFromProgID Method (String, Boolean)

.NET Framework 4

Gets the type associated with the specified program identifier (ProgID), specifying whether to throw an exception if an error occurs while loading the type.

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

Syntax

C++

static member GetTypeFromProgID : 
        progID:string * 
        throwOnError:bool -> Type

Parameters

progID: Type: System.String
The ProgID of the type to get.

throwOnError: Type: System.Boolean
true to throw any exception that occurs.
-or-
false to ignore any exception that occurs.

Return Value

Type: System.Type
The type associated with the specified program identifier (ProgID), if progID is a valid entry in the registry and a type is associated with it; otherwise, a null reference (Nothing in Visual Basic).

Exceptions

Exception	Condition
ArgumentException	progID is a null reference (Nothing in Visual Basic).
COMException	The specified ProgID is not registered.

Remarks

This method is provided for COM support. Program IDs are not used in Microsoft .NET Framework because they have been superseded by the concept of namespace.

Examples
