Retrieves the extension of the catalog file. Namespace: Microsoft.ComponentStudio.ComponentPlatformInterface
Assembly: Microsoft.ComponentStudio.ComponentPlatformInterface (in microsoft.componentstudio.componentplatforminterface.dll)

Usage

Visual Basic
Dim returnValue As String returnValue = OfflineImageInfo.CatalogExtension

Syntax

Visual Basic
Public Shared ReadOnly Property CatalogExtension() As String

C#
public static string CatalogExtension {get;}

C++
public: property static String^ CatalogExtension { String^ get(); }

J#
public static System.String get_CatalogExtension();

JScript
public static function get CatalogExtension() : String;

Property Value

The extension used for the catalog file. The default is .clg.

Example

The following code shows how to open an offline image given a file.

OfflineImage OpenOfflineImage(string file)
{
	OfflineImage image;
	if (!Path.GetExtension(file).ToLower().Equals
		(OfflineImageInfo.CatalogExtension))
	{
		// User selected a .wim file or folder:
		OfflineImageInfo imageInfo;
		if (Directory.Exists(file))
		{
			// User selected a folder:
			imageInfo = Cpi.Instance.GetOfflineImageInfo(file);
	}
		else
		{
			// User selected a .wim file:
			WimInfo wimInfo = Cpi.Instance.OpenWim(file);
			// There could be more than one image in the 
			// WimInfo instance:
			imageInfo = wimInfo.Images[0];
	}
		if (!imageInfo.ValidateCatalog().Succeeded)
			imageInfo.CreateCatalog();
		image = Cpi.Instance.OpenOfflineImage(imageInfo);
}
	else
	{
		// User selected a catalog file:
		image = Cpi.Instance.OpenOfflineImage(file);
}
	return image;
}

Remarks

This method is used to determine the type of file to open in Windows System Image Manager (Windows SIM). For example, if you select a .clg file, you do not need to create a catalog. If you select a folder or a .wim file, you need to verify that a catalog exists, and if not, create a catalog against the .wim file.
