Summary

Represents the error that occurs when an attempt is made to access an element of an array with an index that is outside the bounds of the array.

Description

[Note: The following IL instructions throw IndexOutOfRangeException :

• ldelem.<type>
• ldelema
• stelem.<type>

]

Example

The following example demonstrates an error that causes a IndexOutOfRangeException exception.

using System;
public class IndexRangeTest {
 public static void Main() {
   int[] array = {0,0,0};
   try {
     for (int i = 0; i<4; i++) {
       Console.WriteLine("array[{0}] = {1}",i,array[i]);
     }
   }
   catch (IndexOutOfRangeException e) {
     Console.WriteLine("Error: {0}",e);
   }
 }
}
   

The output is

array[0] = 0
array[1] = 0
array[2] = 0
Error: System.IndexOutOfRangeException: Index was outside the bounds of the array.
   at IndexRangeTest.Main()

IndexOutOfRangeException Constructors

IndexOutOfRangeException() Constructor
IndexOutOfRangeException(System.String) Constructor
IndexOutOfRangeException(System.String, System.Exception) Constructor

Constructs and initializes a new instance of the IndexOutOfRangeException class.

Description

This constructor initializes the System.IndexOutOfRangeException.Message property of the new instance to a system-supplied message that describes the error, such as "An array index is out of range." This message takes into account the current system culture.

The System.IndexOutOfRangeException.InnerException property is initialized to null .

Parameters

message

A String that describes the error. The content of message is intended to be understood by humans. The caller of this constructor is required to ensure that this string has been localized for the current system culture.

Description

This constructor initializes the System.IndexOutOfRangeException.Message property of the new instance using message. If message is null , the System.IndexOutOfRangeException.Message property is initialized to the system-supplied message provided by the constructor that takes no arguments. The System.IndexOutOfRangeException.InnerException property is initialized to null .

Parameters

message

A String that describes the error. The content of message is intended to be understood by humans. The caller of this constructor is required to ensure that this string has been localized for the current system culture.

innerException

An instance of Exception that is the cause of the current exception. If innerException is non-null, then the current exception was raised in a catch block handling innerException .

Description

This constructor initializes the System.IndexOutOfRangeException.Message property of the new instance using message, and the System.IndexOutOfRangeException.InnerException property using innerException. If message is null , the System.IndexOutOfRangeException.Message property is initialized to the system-supplied message provided by the constructor that takes no arguments.
