I have an string array of size 10:
[0] = "1,0000000" [1] = "479,00000" .... [9] = "145,0".
I want to remove the trailing ",00000" of the first 9 elements with regex and linq. Please help.

Basically I would do this like that :
var yourArray = new string[10];
var yourResult = yourArray.Take(9).Select(s => s.Split(',')[0]).ToArray();
But you can replace the Select method content with a Regex call if you wish.

My answer is very basic, but so is his question.

There will be no such cases. I did it in a lil bit different way with .Select(x => Regex.Replace(x, ",0+$", "")).ToArray(). Anyway...good to know. Nice!
Use a for-loop and string methods like IndexOf and Substring:
for(int i = 0; i < Math.Min(array.Length, 9); i++)
{
int commaIndex = array[i].IndexOf(",");
if(commaIndex >= 0) array[i] = array[i].Substring(0, commaIndex);
}

You can simply try
data.forEach(x => x.replace("ABC", "'"));

Regex.Replace(string, ",0+$", "")add*instead of+if necessary.
