i need to create a function that will capture the values which user pasted from excel. i only able to get the first row, however how to get the second row and onward?

this is my code:

C#

protected void btnSubmit_Click(object sender, EventArgs e)
{
    string rowA, rowB, rowC;

    string str = this.TextBox1.Text;
    string[] tokens = str.Split('\t');
    string retVal = tokens[0] + " " + tokens[1];
    rowA = retVal; //result for first row
    rowB = "";     //result for second row
    rowC = "";     //result for third row
}

sample Data user paste from excel:

User ID	Column1	Column2	Column3	Column4
1	100	120	110	80
2	80	90	95	115

Expected result:
rowA = 210 (Column1 + Column3, 001 only)
rowB = 185 (Column2 + Column3, 002 only)
if u notice, the calculation for rowA and rowB is different, the formula is already predefined

please help me, thanks :)

Solution 1

you may have multiple lines

C#

string[] rows = TextBox1.Text.Split (new string[]{System.Environment.NewLine}, StringSplitOptions.None );
string[] row1 = rows[1].Split();
var rowA  = int.Parse(row1[1]) +int.Parse(row1[3]);
string[] row2 = rows[2].Split();
var rowB  = int.Parse(row2[2]) +int.Parse(row2[3]);
