將DataGridView導出為CSV文本文件

Question

我編寫了以下代碼，但它不起作用（它在我的CSV文件中保存了愚蠢的東西）。 有什么不對？ 我的DataGridView中有兩列。

var strValue = new StringBuilder();

foreach(DataGridViewRow row in dataGridView1.Rows)
{
    strValue.AppendLine(row.Cells[0] + "," + row.Cells[1]);
}

string strFile = Properties.Settings.Default.AutoCompleteFile; //File Path

if (!string.IsNullOrEmpty(strValue.ToString()))
{
    File.WriteAllText(strFile, strValue.ToString(), Encoding.UTF8);
}

這是我在保存的文件中得到的結果：

DataGridViewTextBoxCell {ColumnIndex = 0，RowIndex = 0}，DataGridViewTextBoxCell {ColumnIndex = 1，RowIndex = 0} DataGridViewTextBoxCell {ColumnIndex = 0，RowIndex = 1}，DataGridViewTextBoxCell {ColumnIndex = 1，RowIndex = 1} DataGridViewTextBoxCell {ColumnIndex = 0 ，RowIndex = 2}，DataGridViewTextBoxCell {ColumnIndex = 1，RowIndex = 2} DataGridViewTextBoxCell {ColumnIndex = 0，RowIndex = 3}，DataGridViewTextBoxCell {ColumnIndex = 1，RowIndex = 3} DataGridViewTextBoxCell {ColumnIndex = 0，RowIndex = 4}，DataGridViewTextBoxCell { ColumnIndex = 1，RowIndex = 4} DataGridViewTextBoxCell {ColumnIndex = 0，RowIndex = 5}，DataGridViewTextBoxCell {ColumnIndex = 1，RowIndex = 5} DataGridViewTextBoxCell {ColumnIndex = 0，RowIndex = 6}，DataGridViewTextBoxCell {ColumnIndex = 1，RowIndex = 6} DataGridViewTextBoxCell {ColumnIndex = 0，RowIndex = 7}，DataGridViewTextBoxCell {ColumnIndex = 1，RowIndex = 7} DataGridViewTextBoxCell {ColumnIndex = 0，RowIndex = 8}，DataGridViewTextBoxCell {ColumnIndex = 1，RowIndex = 8} DataGridViewTextBoxCel l {ColumnIndex = 0，RowIndex = 9}，DataGridViewTextBoxCell {ColumnIndex = 1，RowIndex = 9} DataGridViewTextBoxCell {ColumnIndex = 0，RowIndex = 10}，DataGridViewTextBoxCell {ColumnIndex = 1，RowIndex = 10}

當你這樣稱呼時：

strValue.AppendLine(row.Cells[0] + "," + row.Cells[1]);

.Net正在對每個單元格進行“ToString”，而不是它們的值。 這是row.Cells[x]的類型： http ： //msdn.microsoft.com/en-us/library/system.windows.forms.datagridviewcell.aspx

使用Value屬性可能會解決您的問題：

strValue.AppendLine(row.Cells[0].Value + "," + row.Cells[1].Value);
