ParserErrorCollection.IndexOf Method

Gets the index of the specified ParserError object in the collection.

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

public int IndexOf(
	ParserError value
)

Parameters

value
Type: System.Web.ParserError

The ParserError to locate in the collection.

Return Value

Type: System.Int32
The zero-based index of the ParserError objects within the collection; otherwise, 1 if the ParserError is not in the collection.

Use the IndexOf method to determine the index of a ParserError object within the collection. This is useful to determine the index of each ParserError when you iterate through the collection by using the IEnumerator object returned by the GetEnumerator method.

The following code example demonstrates how to locate the index of a ParserError object at the specified index in a ParserErrorCollection collection.

// 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);
