title: Declare vector in C#
body: <pre><code>private Vector addTwoVectorsExample() {
      // Create two Vector structures.
      Vector vector1 = new Vector(20, 30);
      Vector vector2 = new Vector(45, 70);
      Vector vectorResult = new Vector();
  
      // Add the vectors together. 
      // vectorResult is equal to (65, 100).
      vectorResult = Vector.Add(vector1, vector2);
  
      return vectorResult;
  
  }
  </code></pre>
  
  <p>When i declare, it show error in <strong>Vector vector1 = new Vector(20, 30);</strong></p>

    <p>How can i call vector in <strong>C#</strong>.</p>
