Summary

Represents the error that occurs when an attempt is made to load a Assembly from a file with an invalid file image.

Description

This exception is thrown when the file image of an executable program is invalid. For example, this exception is thrown when unmanaged code is passed to System.Reflection.Assembly.Load(System.String) for loading.

Example

The following example demonstrates an attempt to load an unmanaged executable, which causes the system to throw a BadImageFormatException exception. [Note: The name of the unmanaged executable is "calc".]

using System;
using System.Reflection;

public class BadImageExample {
  public static void Main() {
    try {
      Assembly a = Assembly.Load("calc");
    } 
    catch (BadImageFormatException e) {
      Console.WriteLine("Caught: {0}", e.Message);
    }
  } 
}
The output is

Caught: The format of the file 'calc' is invalid.

public BadImageFormatException();

Summary

Constructs and initializes a new instance of the BadImageFormatException class.

Description

This constructor initializes the System.BadImageFormatException.Message property of the new instance to a system-supplied message that describes the error, such as "Format of the executable or library is invalid." This message takes into account the current system culture.

The System.BadImageFormatException.InnerException and the System.BadImageFormatException.FileName properties of the new instance are initialized to null .

public BadImageFormatException(string message);

Summary

Constructs and initializes a new instance of the BadImageFormatException class.

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

BadImageFormatException(System.String, System.Exception) Constructor

public BadImageFormatException(string message, Exception inner);

Summary

Constructs and initializes a new instance of the BadImageFormatException class.

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

public BadImageFormatException(string message, string fileName);

Summary

Constructs and initializes a new instance of the BadImageFormatException class.

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.
