Remove Last Element Of Sring[]

Actually i have one string from which i have creates string[] in which i used split function. Like this

csvData = str.Split(',');

And after creating string collection i have to create one datarow from it, and had to fill items from string collection. and after that have to add row in table. but when i try with followoing code. it gives me error. because ItemArray=15 and csvdata1.length=16 due to this it gives me error index out of bound exception.

DataRow dr = csvDataTable.NewRow();
for (int j = 0; j < csvData.Length - 1; j++)
{
//fill them
dr.ItemArray = csvdata1;
}
csvDataTable.Rows.Add(dr);
csvDataTable.AcceptChanges();
for this i have tried to create one another string[.
for (int i = 0; i < csvData.Length; i++)
{
csvdata1[i] = csvData[i];
}

how can i remove last element of the string[].
