Module.GetType Method (String, Boolean, Boolean)

Returns the specified type, specifying whether to make a case-sensitive search of the module and whether to throw an exception if the type cannot be found.

Namespace:  System.Reflection
Assembly:  mscorlib (in mscorlib.dll)
public virtual Type GetType(
	string className,
	bool throwOnError,
	bool ignoreCase


Type: System.String
The name of the type to locate. The name must be fully qualified with the namespace.
Type: System.Boolean
true to throw an exception if the type cannot be found; false to return null.
Type: System.Boolean
true to perform a case-insensitive search; otherwise, false.

Return Value

Type: System.Type
The specified type, if the type is declared in this module; otherwise, null.

className is null.


The class initializers are invoked and an exception is thrown.


className is a zero-length string.


throwOnError is true, and the type cannot be found.


className requires a dependent assembly that could not be found.


className requires a dependent assembly that was found but could not be loaded.


The current assembly was loaded into the reflection-only context, and className requires a dependent assembly that was not preloaded.


className requires a dependent assembly, but the file is not a valid assembly.


className requires a dependent assembly which was compiled for a version of the runtime later than the currently loaded version.

The throwOnError parameter affects only what happens when the type is not found. It does not affect any other exceptions that might be thrown. In particular, if the type is found but cannot be loaded, TypeLoadException can be thrown even if throwOnError is false.


If the type has been forwarded to another assembly, it is still returned by this method.

A type can be retrieved from a specific module using Module.GetType. Calling Module.GetType on the module that contains the manifest will not search the entire assembly. To retrieve a type from an assembly, regardless of which module it is in, you must call Assembly.GetType.

Platform Notes

Silverlight for Windows Phone Silverlight for Windows Phone

 GetType does not throw ArgumentException when an empty string is passed as className. Instead, it returns null.

The following example attempts to get a type that does not exist in the currently executing module. The throwOnError parameter is true, so an exception is thrown.

using System;
using System.Reflection;

class Example
    public static void Demo(System.Windows.Controls.TextBlock outputBlock)
        Module[] moduleArray;

        moduleArray = Assembly.GetExecutingAssembly().GetModules();

        Module myModule = moduleArray[0];

        Type myType;

            myType = myModule.GetType("UnknownType", true, false);
            outputBlock.Text += String.Format("Found type: {0}\n", myType.ToString());
        catch (Exception ex)
            outputBlock.Text += String.Format("Caught {0}: {1}\n", 

/* This example produces output similar to the following:

Caught TypeLoadException: Could not load type 'UnknownType' from assembly 'SilverlightApplication, Version=, Culture=neutral, PublicKeyToken=null'.
