HttpResponseHeaderCollection.TryGetValue method

Applies to Windows and Windows Phone

Returns a value that indicates whether a specified key exists in the HttpResponseHeaderCollection. If an item with that key exists, the item is retrieved as an out parameter.

Syntax


public bool TryGetValue(
  string key, 
  out string value
)

Parameters

key

Type: System.String

The key to check for in the HttpResponseHeaderCollection.

value (out parameter)

Type: System.String

The item, if it exists. Contains null if the item does not exist in the HttpResponseHeaderCollection.

Return value

Type: System.Boolean

true if an item with that key exists in the HttpResponseHeaderCollection; otherwise, false.

Remarks

The TryGetValue method is available when you need to work with an HTTP header on an HTTP response that doesn't have a strongly-typed class for the HTTP header. If there is a strongly-typed implementation of the HTTP header, then the methods and properties on the strongly-typed class should be used instead of the TryGetValue method.
