ParserErrorCollection.Contains(ParserError) Method

public:
 bool Contains(System::Web::ParserError ^ value);

public bool Contains (System.Web.ParserError value);

member this.Contains : System.Web.ParserError -> bool

Public Function Contains (value As ParserError) As Boolean

Parameters

Returns

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

Examples

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);

' Test for the presence of a ParserError in the 
' collection, and retrieve its index if it is found.
Dim testError As New ParserError("Error", "Path", 1)
Dim itemIndex As Integer = -1
If collection.Contains(testError) Then
  itemIndex = collection.IndexOf(testError)
End If

Remarks

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.
