Determines whether the ParserError object is located in the collection.
public:
bool Contains(System::Web::ParserError ^ value);public bool Contains (System.Web.ParserError value);member this.Contains : System.Web.ParserError -> boolPublic Function Contains (value As ParserError) As BooleanParameters
- value
- ParserError
The ParserError to locate in the collection.
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.
