This article describes the difference between two-dimensional arrays in C# and Java, and is shared with you for your reference. The specific analysis is as follows:
Using two-dimensional arrays in Java can be used as follows:
Copy the codeThe code is as follows:
public class Array2D{
public static void main(String[] args){
int myInt[][]=new int[5][10];
//Tranquility, assign values to each array in the array
for(int i=0;i<;i++){
for(int j=0;j<myInt[0].length;j++){
myInt[i][j]=i*j;
}
}
("="++",myInt[0].length="+myInt[0].length);
//The lower and upper limits of each dimension of the output array
for(int i=0;i<;i++){
for(int j=0;j<myInt[0].length;j++){
("myInt["+i+"]["+j+"]="+myInt[i][j]);
}
}
}
}
public static void main(String[] args){
int myInt[][]=new int[5][10];
//Tranquility, assign values to each array in the array
for(int i=0;i<;i++){
for(int j=0;j<myInt[0].length;j++){
myInt[i][j]=i*j;
}
}
("="++",myInt[0].length="+myInt[0].length);
//The lower and upper limits of each dimension of the output array
for(int i=0;i<;i++){
for(int j=0;j<myInt[0].length;j++){
("myInt["+i+"]["+j+"]="+myInt[i][j]);
}
}
}
}
Regarding the above code, I personally think that this can be done in C#, but in fact it is wrong. In C# int[][] myInt declares an interlaced array and declares a two-dimensional array to declare int[,] myInt. If the above code is replaced with C#, it needs to be expressed as follows:
Copy the codeThe code is as follows:
class clsArrat2D
{
/// <summary>
/// The main entry point of the application.
/// </summary>
[STAThread]
static void Main(string[] args)
{
int[,] myInt=new int[5,10];
//Tranquility, assign values to each array in the array
for(int i=(0);i<=(0);i++)
{
for(int j=(1);j<=(1);j++)
{
myInt[i,j]=i*j;
}
}
//The lower limit and upper limit of each dimension of the output array
for(int i=0;i<;i++)
{
("{0} {1} {2}", i, (i), (i));
}
//Travel, output the number of each element in the two-dimensional array
for(int i=(0);i<=(0);i++)
{
for(int j=(1);j<=(1);j++)
{
("myInt[{0},{1}]={2}",i,j,myInt[i,j]);
}
}
();
}
}
{
/// <summary>
/// The main entry point of the application.
/// </summary>
[STAThread]
static void Main(string[] args)
{
int[,] myInt=new int[5,10];
//Tranquility, assign values to each array in the array
for(int i=(0);i<=(0);i++)
{
for(int j=(1);j<=(1);j++)
{
myInt[i,j]=i*j;
}
}
//The lower limit and upper limit of each dimension of the output array
for(int i=0;i<;i++)
{
("{0} {1} {2}", i, (i), (i));
}
//Travel, output the number of each element in the two-dimensional array
for(int i=(0);i<=(0);i++)
{
for(int j=(1);j<=(1);j++)
{
("myInt[{0},{1}]={2}",i,j,myInt[i,j]);
}
}
();
}
}
In general, I feel that C# is doing a bad job. It is obviously just imitating C++ and Java, but people declare two-dimensional arrays in this way. Microsoft is unconventional here. If you accidentally fall, you don’t know why. You are not used to it when you first use it.
I hope this article will be helpful to beginners' C# programming learning.
