Examples of basic usage of C# two-dimensional arrays

This article describes the basic usage of C# two-dimensional arrays. Share it for your reference, as follows:

//Define arraystring[,] classes = new string[5, 2]; 
//Correct C# How to use two-dimensional arraysclasses[i, 0] = "";//Incorrect usage methodclasses[i][0]="";

It is said that this form of C# two-dimensional array is called a sawtooth array.

An example for reference:

// Declare a jagged array with two elementsint[][] myArray = new int[2][];  
// The first element is an array containing five elements// Initialize myArray[0]myArray[0] = new int[5] {1,3,5,7,9}; 
// The second element is an array with 4 elements// Initialize myArray[1]myArray[1] = new int[4] {0, 2, 4, 6}; 
// Print out all elements in the array one by onefor (int i=0; i &lt; ; i++)  
{ 
 ("The({0})Arrays: ", i); 
 // Print elements in a one-dimensional array for (int j=0; j &lt; myArray[i].Length; j++) 
 { 
   ("{0} ", myArray[i][j]); 
 } 
 (); 
}

I hope this article will be helpful to everyone's C# programming.
