C# - Generate Random String, and use it Statically? [on hold]

I want to use this -> http://ift.tt/1RYY97N

But seems like it indeed generates everytime a random string, BUT.. I want to use it once and then transfer throughout my entire project the very same unique generated string.. for example.

Utilities.GenerateString(32);
PseudoCode <Generated_Static_String_Should_Go_Here()>
...
"In another Class"
....
MessageBox.Show(Static_String_Generated_Should_Go_Here());
