TagMapInfo Class

Contains a single configuration tag remapping statement. This class cannot be inherited.

Namespace: System.Web.Configuration
Assembly: System.Web (in system.web.dll)

public sealed class TagMapInfo : ConfigurationElement
public final class TagMapInfo extends ConfigurationElement
public final class TagMapInfo extends ConfigurationElement
Not applicable.

The TagMapInfo class allows you to remap the types of tags at compile time. This remapping causes the mapped type to be used in place of the original tag type for all pages and controls in the ASP.NET application in the scope of the configuration file.

The TagMapCollection class allows you to programmatically access and modify the tagMapping subsection of the pages section of a configuration file. Within the tagMappings subsection, you can add and remove mappings between tag types by specifying the fully qualified strong names of the types.


Unlike other attributes and collections in the pages section, tag remapping has no matching ASP.NET page directive.

The following configuration file excerpt shows how to declaratively specify values for several properties of the TagMapInfo class.

           MSPS.Web.dll, Version=''" 

The following code example shows how to use the TagMapCollection class to programmatically modify tag-mapping settings. This code example is part of a larger example provided for the PagesSection class.

// Get all current TagMappings in the collection.
for (int i = 0; i < pagesSection.TagMapping.Count; i++)
  Console.WriteLine("TagMapping {0}:", i);
  Console.WriteLine("  TagTypeName = '{0}'",
  Console.WriteLine("  MappedTagTypeName = '{0}'",

// Add a TagMapInfo object using a constructor.
    new System.Web.Configuration.TagMapInfo(
    "MyNameSpace.MyControl", "MyNameSpace.MyOtherControl"));


Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
