CompilerErrorCollection Class

Represents a collection of CompilerError objects.

Namespace:  System.CodeDom.Compiler
Assembly:  System (in System.dll)

'Declaration
<SerializableAttribute> _
<PermissionSetAttribute(SecurityAction.InheritanceDemand, Name := "FullTrust")> _
Public Class CompilerErrorCollection _
	Inherits CollectionBase
'Usage
Dim instance As CompilerErrorCollection

The CompilerErrorCollection class provides a simple collection object that can be used to store a set of CompilerError objects.

NoteNote:

This class contains an inheritance demand at the class level that applies to all members. A SecurityException is thrown when the derived class does not have full-trust permission. For details about inheritance demands, see Inheritance Demands.

The following example demonstrates how to use the CompilerErrorCollection class. The example creates a new instance of the class and uses several methods to add statements to the collection, return their index, and add or remove attributes at a specific index point.

' Creates an empty CompilerErrorCollection. 
Dim collection As New CompilerErrorCollection()

' Adds a CompilerError to the collection.
collection.Add(New CompilerError("Testfile.cs", 5, 10, "CS0001", "Example error text"))

' Adds an array of CompilerError objects to the collection. 
Dim errors As CompilerError() = {New CompilerError("Testfile.cs", 5, 10, "CS0001", "Example error text"), New CompilerError("Testfile.cs", 5, 10, "CS0001", "Example error text")}
collection.AddRange(errors)

' Adds a collection of CompilerError objects to the collection. 
Dim errorsCollection As New CompilerErrorCollection()
errorsCollection.Add(New CompilerError("Testfile.cs", 5, 10, "CS0001", "Example error text"))
errorsCollection.Add(New CompilerError("Testfile.cs", 5, 10, "CS0001", "Example error text"))
collection.AddRange(errorsCollection)

' Tests for the presence of a CompilerError in the  
' collection, and retrieves its index if it is found. 
Dim testError As New CompilerError("Testfile.cs", 5, 10, "CS0001", "Example error text")
Dim itemIndex As Integer = -1
If collection.Contains(testError) Then
    itemIndex = collection.IndexOf(testError)
End If 

' Copies the contents of the collection, beginning at index 0,  
' to the specified CompilerError array. 
' 'errors' is a CompilerError array.
collection.CopyTo(errors, 0)

' Retrieves the count of the items in the collection. 
Dim collectionCount As Integer = collection.Count

' Inserts a CompilerError at index 0 of the collection.
collection.Insert(0, New CompilerError("Testfile.cs", 5, 10, "CS0001", "Example error text"))

' Removes the specified CompilerError from the collection. 
Dim [error] As New CompilerError("Testfile.cs", 5, 10, "CS0001", "Example error text")
collection.Remove([error])

' Removes the CompilerError at index 0.
collection.RemoveAt(0)
