C# 循环到 Excel 中的特定行

Question

Can anyone help me I want my C# code to start loop and print at row number 5 in my Excel file.

Here is my current code:

            DataColumnCollection dataColumnCollection = dataTable.Columns;

            for (int i = 1; i <= dataTable.Rows.Count + 1; i++)
            {
                for (int j = 1; j <= dataTable.Columns.Count; j++)
                {
                    if (i == 1)
                        excelApplication.Cells[i, j] = dataColumnCollection[j - 1].ToString();
                    else
                        excelApplication.Cells[i, j] = dataTable.Rows[i - 2][j - 1].ToString();
                }

Here is my sample data: sample data

first of all arrays and lists the like start at 0 in most cases.

In your case if you want to start at row 5, simply increment the start with 5.

            const int start = 5;
            int end = datadataTable.Rows.Count;
            for (int i = 0 + start; i < end; i++) // loop from 5..end
            {

                for (int j = 1; j <= dataTable.Columns.Count; j++)
                {
                    if (i == 1)
                        excelApplication.Cells[i, j] = dataColumnCollection[j - 1].ToString();
                    else
                        excelApplication.Cells[i, j] = dataTable.Rows[i - 2][j - 1].ToString();
                }
