Hi,
Here is the improved version of Solution1,
string result;
string fileName = "15.Crank vs.Cams Bank 2";
string[] v = fileName.Split(new char[] { '.' }, StringSplitOptions.RemoveEmptyEntries);
for(i =1; i<v.length;i++)>
{
result += v[i];
}
Here in for loop i have ignore first value and then append rest of the value. another solution is to remove first value from result array and then use join to combine all other values.
Hope it works for you,
Thanks
