C# Program to Perform Matrix Multiplication

This C# Program Performs Matrix Multiplication. Here The matrix multiplication is performed if the number of columns of the first matrix is equal to the number of rows of the second matrix. For loop is used to display the values in a matrix format.

Here is source code of the C# Program to Perform Matrix Multiplication. The C# program is successfully compiled and executed with Microsoft Visual Studio. The program output is also shown below.
