C# Microsoft Solver Foundation load/read data from a file or using sets

Hi Everyone,

I need help on using Microsoft solver foundation to solve linear programming models.
Does anyone one how to load/read data from a file and then use that data to solve a linear programming model using Microsoft solver foundation in C#?

Here is my code in C# using Microsoft solver foundation to solve a linear program. But I don't want to write all constraints one by one, I want to load/read data from a file then use it to solve this linear model.

If anyone knows, PLEASE help me!!!!

Code:
