Exception in exporting to excel

Using c#.net I am exporting data from labels in my fo开发者_运维技巧rm to excel. The code is as follows:

Excel.Font font = range.Font;
 font.Color =Color.Black;

While using this code, I am getting an exception

"Methods with System.Color parameters or return type cannot be invoked via IDispatch".

Please help me solve this.
