Module.GetType Method (String, Boolean)

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Returns the specified type, searching the module with the specified case sensitivity.

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

Syntax

'Declaration
<ComVisibleAttribute(True)> _
Public Overridable Function GetType ( _
    className As String, _
    ignoreCase As Boolean _
) As Type

[ComVisibleAttribute(true)]
public virtual Type GetType(
    string className,
    bool ignoreCase
)

Parameters

className
Type: System.String
The name of the type to locate. The name must be fully qualified with the namespace.

ignoreCase
Type: System.Boolean
true to perform a case-insensitive search; otherwise, false.

Return Value

Type: System.Type
The given type, if the type is in this module; otherwise, nulla null reference (Nothing in Visual Basic).

Exceptions

Exception	Condition
ArgumentNullException	className is nulla null reference (Nothing in Visual Basic).
TargetInvocationException	The class initializers are invoked and an exception is thrown.
ArgumentException	className is a zero-length string.
FileNotFoundException	className requires a dependent assembly that could not be found.
FileLoadException	className requires a dependent assembly that was found but could not be loaded. -or- The current assembly was loaded into the reflection-only context, and className requires a dependent assembly that was not preloaded.
BadImageFormatException	className requires a dependent assembly, but the file is not a valid assembly. -or- className requires a dependent assembly which was compiled for a version of the runtime later than the currently loaded version.

Remarks

Note:
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

GetType does not throw ArgumentException when an empty string is passed as className. Instead, it returns nulla null reference (Nothing in Visual Basic).

Examples

The following example gets a type in the currently executing module, specifying a string that has incorrect casing and specifying true for the ignoreCase parameter so that case is ignored.

Note:
To run this example, see Building Examples That Use a Demo Method and a TextBlock Control.

Imports System.Reflection

Class Example
    Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
        Dim moduleArray() As [Module]

        moduleArray = [Assembly].GetExecutingAssembly().GetModules()

        Dim myModule As [Module] = moduleArray(0)

        Dim myType As Type

        myType = myModule.GetType("SILVERlightApplication.example", True)
        outputBlock.Text += String.Format("Found type: {0}" & vbLf, myType.ToString())
    End Sub 
End Class 

' This example produces output similar to the following:
'
'Found type: SilverlightApplication.Example

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("example", true);
        outputBlock.Text += String.Format("Found type: {0}\n", myType.ToString());
    }
}

/* This example produces output similar to the following:

Found type: Example
 */
