[Solved] Error: System.IndexOutOfRangeException: Index was outside the bounds of the array [duplicate]

Your stringArray contains less than two elements.That is your problem, you need to make sure it contains at least two elements before switch statement.BTW, if you just want to append a dot to the end, you don’t need String.Split, just use Insert method:

string str  = row["Version"].ToString();
str = str.Insert(str.Length, ".");

switch(str)
{
   ...
}

Or simply use string concatenation: string str = row["Version"].ToString() + ".";
