ParserErrorCollection.Contains Method

Note: This method is new in the .NET Framework version 2.0.

Determines whether the ParserError object is located in the collection.

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

public bool Contains (
	ParserError value
public boolean Contains (
	ParserError value
public function Contains (
	value : ParserError
) : boolean



The ParserError to locate in the collection.

Return Value

true if the ParserError is in the collection; otherwise, false.

You cannot add the same ParserError object to the collection more than once. However, attempting to add a ParserError object more than once will not throw an exception. Instead, the addition will fail. In this case, the Add method will return a value of –1. However, the AddRange and Insert methods do not have return values. When adding ParserError objects by using one of these methods, use the Contains method to determine whether a particular ParserError object is already in the collection.

The following code example demonstrates how to search for an instance of a specified ParserError object in a ParserErrorCollection object.

// Test for the presence of a ParserError in the 
// collection, and retrieve its index if it is found.
ParserError testError = new ParserError("Error", "Path", 1);
int itemIndex = -1;
if (collection.Contains(testError))
  itemIndex = collection.IndexOf(testError);
