在Excel C＃上的多个单元格周围添加边框

Question

I am currently using Microsoft.Office.Core; and using Excel = Microsoft.Office.Interop.Excel; to export my data from windows form to excel to export data from windows form c# to excel

Is there any chance to add a border on selected cells like How i need it to be

Answer 1

Sure, heres a function I made for the same thing

/// <summary>
/// Puts a border around range
/// </summary>
/// <param name="ws">Excel worksheet</param>
/// <param name="r1">First Row</param>
/// <param name="c1">First Column</param>
/// <param name="r2">Last Row</param>
/// <param name="c2">Last Column</param>
/// <param name="weight">Border Brush Weight</param>
public void BorderRange(Worksheet ws, int r1, int c1, int r2, int c2, XlBorderWeight weight = XlBorderWeight.xlThin)
{
    Range r = ws.Range[ws.Cells[r1, c1], ws.Cells[r2, c2]];
    r.BorderAround2(Microsoft.Office.Interop.Excel.XlLineStyle.xlContinuous, weight);
}

You'll need to call it a few times to put the borders round the ranges you need.
