The ParserErrorCollection class provides methods and properties that you can use to manage a collection of ParserError objects. For example, you can add a set of parser errors to a collection upon parsing while using a custom BuildProvider object to report all parse exceptions caught during parsing.

To add parser errors to, remove them from, or locate them in a collection, use the following:

  • The Add method to add a single ParserError object to the collection.

  • The AddRange methods to add multiple ParserError objects to the collection.

  • Both the Insert method and the Item property, which is the ParserErrorCollection indexer, to add a single ParserError object to the collection at the specified index.

Additionally, you can use the ParserErrorCollection class to do the following:

The following code example demonstrates how to use the ParserErrorCollection methods.

// Create an empty ParserErrorCollection.
ParserErrorCollection collection = new ParserErrorCollection();

// Add a ParserError to the collection.
collection.Add(new ParserError("ErrorName", "Path", 1));

// Add an array of ParserError objects to the collection.
ParserError[] errors = 
    { new ParserError("Error 2", "Path", 1), 
    new ParserError("Error 3", "Path", 1) };
collection.AddRange(errors);

// Add a collection of ParserError objects to the collection.
ParserErrorCollection errorsCollection = new ParserErrorCollection();
errorsCollection.Add(new ParserError("Error", "Path", 1));
errorsCollection.Add(new ParserError("Error", "Path", 1));
collection.AddRange(errorsCollection);

// 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);

// Copy the contents of the collection to a
// compatible array, starting at index 0 of the
// destination array. 
ParserError[] errorsToSort = new ParserError[5];
collection.CopyTo(errorsToSort, 0);

// Retrieve the count of the items in the collection.
int collectionCount = collection.Count;

// Insert a ParserError at index 0 of the collection.
ParserError error = new ParserError("Error", "Path", 1);
collection.Insert(0, error);

// Remove the specified ParserError from the collection.
collection.Remove(error);

// Remove the ParserError at index 0.
collection.RemoveAt(0);
