// 5 is the size of the array
string[] names = new string[5];
names[0] = "Minhajur";
names[5] = "Khan";   // Throws System.IndexOutOfRangeException 

// Add two elements, keeping the existing values
Array.Resize(ref names, 7);

float[,] twoD = new float[rows, cols];
twoD[2,0] = 4.5f; 

int[][] jagged = new int[3][] { 
  new int[5], new int[2], new int[3] };
jagged[0][4] = 5;
