<summary>
<para> Creates a copy of the current instance.
</para>
</summary>
<returns>
<para> A <see cref="T:System.Object" /> of the same type as the current instance, containing
copies of the non-static members of the current instance.
</para>
</returns>
<remarks>
<para>The exact behavior of this method is unspecified. The intent
of the method is to provide a mechanism that constructs
instances that
are copies of the current instance, without regard for class-specific definitions of the term
"copy". </para>
<para>
<block subset="none" type="note"> Use the <see cref="M:System.Object.MemberwiseClone" />
method to create a shallow copy of an object. For more information, see <see cref="M:System.Object.MemberwiseClone" /> . </block>

<para>
<block subset="none" type="behaviors"> This method is required to return
an instance of the same type as the current instance. </block>
</para>
<para>
<block subset="none" type="overrides"> Implement this method to provide
class-specific copying behavior. </block>

<para>
<block subset="none" type="usage"> Use the <see cref="M:System.ICloneable.Clone" /> method
to obtain a copy of the current instance. </block>
</para>
</remarks>
<example>
<para>The following example shows an implementation of <see cref="M:System.ICloneable.Clone" /> that
uses the <see cref="M:System.Object.MemberwiseClone" />
method to create a copy of
the current instance.</para>
<code lang="C#">using System;
class MyClass :ICloneable {
public int myField;
public MyClass() {
myField = 0;
}
public MyClass(int value) {
myField = value;
}
public object Clone() {
return this.MemberwiseClone();
}
}
public class TestMyClass {
public static void Main() {
MyClass my1 = new MyClass(44);
MyClass my2 = (MyClass) my1.Clone();
Console.WriteLine("my1 {0} my2 {1}",my1.myField, my2.myField);
my2.myField = 22;
Console.WriteLine("my1 {0} my2 {1}",my1.myField, my2.myField);
