Microsoft Interop: Excel Column Names

问题

I am using Microsoft Interop to read the data.

In excel-sheet the column-names are like A,B,C,D,....,AA,AB,.... and so on. Is there any way to read this column-names?

If you need any other info please let me know.

Regards, Priyank

     Excel.Application xlApp = new Excel.Application();
     Excel.Workbook xlWorkbook = xlApp.Workbooks.Open("workbookname");
     Excel.Worksheet xlWorksheet = xlWorkbook.Sheets[1]; // assume it is the first sheet
     int columnCount = xlWorksheet.UsedRange.Columns.Count;
     List<string> columnNames = new List<string>();
     for (int c = 1; c < columnCount; c++)
     {
         if (xlWorksheet.Cells[1, c].Value2 != null)
         {
             string columnName = xlWorksheet.Columns[c].Address;
             Regex reg = new Regex(@"(\$)(\w*):");
             if (reg.IsMatch(columnName))
             {
                 Match match = reg.Match(columnName);             
                 columnNames.Add(match.Groups[2].Value);
             }                      
        }
     }

This will put each column name in a List<string> which you can then bind to a drop down box.

You can also Read Column By index

let your Excel work Sheet object is "excelWorksheet" then you can access it as

for setting a value you can use

excelWorksheet.Cells[rowindex, columnindex].Value = "test";

for getting a value you can use

string result = excelWorksheet.Cells[rowindex, columnindex].Value ;

Remember that fields are dynamically generated so it may show error in writing your code but ignore that

for example you want to set text in excel sheet row 1 & column 2 then

excelWorksheet.Cells[1, 2].Value = "test";

I have used it & it works perfectly
