Jagged Array is an "Array of Arrays". More information at MSDN specific to .Net:

May be this answer help to you.....

Jagged Array is an array, with each of its element as an array. Each of its element can be of different size or dimension.

Suppose, in below code we are declaring an array having 3 elements, and each of its element is an array itself, and they are of different size..

Eg:

int[][] x = new int[3][];
x[0] = new int[1];
x[1] = new int[10];
x[2] = new int[15];

It's an array of arrays, where the sub-arrays may have different sizes. For example:

string[][] jagged = new string[][] {
    new string[] { "one" },
    new string[] { "two", "elements" },
    new string[] { "this", "has", "three" },
};

Compare that with a rectangular array, which doesn't have "sub-arrays" but is just a genuine two-dimensional single array:

string[,] rectangular = new string[,] {
    // These must all have the same length
    { "a", "b" },
    { "c", "d" },
    { "0", "1" }
};

A jagged array is an array of arrays (specifically a one dimensional array of one dimensional arrays).

The term "jagged" comes from that the inner arrays can be of diffent length, compared to a two dimensional array where the data in each dimension is always the same length.

Have a look at the microsoft msdn library, it has loads of small examples and explains them perfectly.

http://msdn.microsoft.com/en-us/library/2s05feca.aspx

"A jagged array is an array whose elements are arrays. The elements of a jagged array can be of different dimensions and sizes."
