with a 2 dimentional array you can use 2 loops to fill your arrays:

int[,] arrays = new int[60,100];
for(int arraynumber = 0; arraynumber < 60; arraynumber++)
{
    for(int i = 0; i< 100;i++)
    {
        arrays[arraynumber,i] = arrays[0,i];
    }
}

you can also use an array of arrays

I doubt if 2D array int[,] arrays is a good choice here. What if arrays in the question are of different lengths? Jugged array int[][] arrays looks far better.

Thomas Over a year ago

you should use an array of arrays if the arrays don't have the same size

I'm not shure, but I think an array of arrays is slower than a 2d array, but I'm realy not shure

R.zeiwald Over a year ago

All arrays have same length,i will try your solution @Thomas

I have no IDE here @ the moment, so maybe there is a sintaxerror

Try this

var sourceArray = new string[]{"1","2","3","4","5","6"};
var destArrays = new string[4,sourceArray.Length];
int innerIndex = 0;
int outerIndex = 0;

while(outerIndex<destArrays.GetLength(0))
{
    while (innerIndex<sourceArray.Length && sourceArray[innerIndex] != " ")
  {
      destArrays[outerIndex,innerIndex] = sourceArray[innerIndex];
      innerIndex++;
  }
  innerIndex = 0;
  outerIndex++;
}

A simple solution:

string[][] arrays = new string[][] { array1, array2, array3 };

foreach (string[] arr in arrays) {
    // do staff here
}

i did't get your code ,how do i change name from array1 to array2 to assign values to arrays

quantummind Over a year ago

You don't change it. You list all the arrays in the { } brackets and the outer forech loop goes through all the array you have listed.
