The private field 'class member' is never used
A private variable was declared but never referenced. A common way to generate this warning is when you declare a private member of a class and do not modify the value of the member inside the class. To resolve a warning of this nature, either remove the field or add the public keyword to the field's declaration.
The following sample generates CS0169:
public class clx { int i; // CS0169 // try the following line instead // public int i; public static void Main() { } }
