Passing an array to a function as a string parameter

I would like to be able to pass a 2-dimensional array to a function as a string parameter. In the called function I would like to be able to convert the string back into a 2-dimensional array. Example

Function1 {
int [,] TheArray[10,10];
Function2(TheArray.ToString();
}
Function2 (string parm) {
.... In here I would like to be able to convert parm back into a 2-dimensional int array. How do I do this
}

Appreciate your help,
Alex
 
You could use the String.Join and String.Split. Although you probably have
your reason for doing this, keep in mind that this will not be as efficient
as just passing the reference to the array.

Yes, you can do it by coding it yourself. Is there a reason you just don't
pass the array? Conforming to an existing interface?

good luck,
kevin aubuchon

int [,] ar = new int[2,2];
int [,] az = new int[2,2];

ar[0,0] = 1;
ar[0,1] = 2;
ar[1,0] = 3;
ar[1,1] = 4;

StringBuilder sb = new System.Text.StringBuilder (100);
for (int i = 0; i < 2;i++)
{
for (int j=0; j < 2;j++)
{
sb.Append (ar[i,j].ToString("##") + ";");
}
}
string s = sb.ToString ();
char [] cs = {char.Parse (";")};

string [] lines = s.Split (cs);

for (int i = 0; i < 2;i++)
{
for (int j=0; j < 2;j++)
{
az[i,j] = Int32.Parse (lines[i * 2 + j]);
}
}

Another alternative is to use the BinaryFormatter.
eg :.
==
using System.IO;
using System.Runtime.Serialization.Formatters.Binary;
...
...
private string ConvertToBase64String(int[,] data)
{
BinaryFormatter formatter = new BinaryFormatter();
using(MemoryStream ms = new MemoryStream())
{
formatter.Serialize(ms, data);

byte[] res = ms.ToArray();
return Convert.ToBase64String(res);
}
}

private int[,] ConvertFromBase64String(string str)
{
byte[] res = Convert.FromBase64String(str);

BinaryFormatter formatter = new BinaryFormatter();

using(MemoryStream ms = new MemoryStream(res))
{
return (int[,])formatter.Deserialize(ms);
}
}
==

HTH,
Stephen
