How to convert an integer array to a matrix in c#

I have an integer array named resp I want to rewrite/convert it as/to a row matrix with name resp.

int[] resp= {1, 0, 1, 0};

I am using the Mathnet.Numerics library.

How can I do that?

In Mathnet, you are not able to initialize an array of integers. As it is, there's in limited support available for this. If you tried, you would get this: 

Unhandled Exception: System.TypeInitializationException: The type initializer 
for 'MathNet.Numerics.LinearAlgebra.Vector`1' threw an exception. ---> 
System.NotSupportedException: Matrices and vectors of type 'Int32' 
are not supported. Only Double, Single, Complex or Complex32 are supported at this point.

You can initialize a vector with similar values (with doubles) like this: 

var resp = new [] {1.0, 0.0, 1.0, 0.0};
var V = Vector<double>.Build;
var rowVector = V.DenseOfArray(resp);

In order to build a matrix, you would need a multi-dimensional array.
