<para>Represents the error that occurs when there is an
attempt to access a method outside the scope in which access is permitted.</para>
</summary>
<remarks>
<para>
<block subset="none" type="note">This exception is
thrown when the access level of a method in a class library is changed, and one
or more assemblies referencing the library have not been recompiled. This exception is also thrown when an attempt to invoke a
method via reflection fails because the caller does not have the required
permissions.</block>
</para>
</remarks>
<example>
<para>The following example demonstrates a scenario under
which <see cref="T:System.MethodAccessException" />
is thrown.</para>
<para>The following code contains a class with a public method (MyMethod). This
class is compiled into a class library.</para>
<code lang="C#">using System;
namespace TestNameSpace
{
public class Class1
{
public Class1()
{
Console.WriteLine ("Constructing with public method.");
}
public void MyMethod ()
{
Console.WriteLine ("Calling MyMethod.");

<para>The following code references the class library above, and accesses
TestNameSpace.Class1.MyMethod. This code is compiled into an application.</para>
<code lang="C#">using System;
using TestNameSpace;
class AppTest
{
public static void Main()
{
Class1 test = new Class1();
test.MyMethod();

</code>
<para>The output of the application is</para>
<c>
<para>Constructing with public method.</para>
<para>Calling MyMethod.</para>
</c>
<para>The code for the class library is changed and recompiled so that TestNameSpace.Class1.MyMethod is no longer public. The following code changes
MyMethod from public to private. </para>
