ComboBox顯示DataRowView而不是實際值

Question

我的組合框有問題，我試圖從myExcel.xls文件中的數據填充它，但它在組合框中顯示System.Data.DataRowView而不是實際值。這是我的代碼：

Application excelApp = new ApplicationClass();
string strWB = "myExcel.xls";
string strWBPath = "D:\\TEMP\\";

// Opening Excel file
Workbook workbook = excelApp.Workbooks.Open(strWBPath + strWB, 0, true, 5, "", "", true, XlPlatform.xlWindows, "\t", false, false, 0, true, 1, 0);

Worksheet worksheet = (Worksheet)workbook.Sheets.get_Item(1);
Range range = worksheet.UsedRange;

int column = 0;
int row = 0;

DataTable dt = new DataTable();
dt.Columns.Add("Agent Name");

for (row = 2; row <= range.Rows.Count; row++)
{
    DataRow dr = dt.NewRow();
    for (column = 1; column <= range.Columns.Count; column++)
    {
        dr[column - 1] = (range.Cells[row, column] as Range).Value2.ToString();
    }
    dt.Rows.Add(dr);
}
workbook.Close(true, null, null);
excelApp.Quit();

//  dataGridView1.DataSource = dt;

comboBox1.DisplayMember = "FirstName";
comboBox1.ValueMember = "Sheet1";
comboBox1.DataSource = dt;

Answer 1

Value2是一個對象。 這樣，ToString將返回默認名稱，而不是值。 嘗試使用“作為字符串”而不是“ .ToString”。

Answer 2

有什么理由不將comboBox1.DataSource綁定到列表嗎？ 就像是：

dt.AsEnumerable().Select(x => x["FirstName"].ToString()).ToList();
