[英]C# Cannot save textbox data to excel document
As far as I know, there are no errors to speak of in the following code: 据我所知,以下代码中没有错误可言:
private Excel.Application Xls;
private Excel.Workbooks XlsB;
private Excel.Workbook WB;
private Excel.Worksheet WS;
private Excel.Sheets WBs;
private void btnPrint_Click(object sender, EventArgs e)
{
try
{
Xls = new Excel.Application();
XlsB = Xls.Workbooks;
WB = XlsB.Open(lblPath.Text, 0, false, 5, "", "", true,
XlPlatform.xlWindows, "\t", false, false, 0, true, 1, 0);
Sheets WBs = WB.Worksheets;
Worksheet WS = WBs.get_Item(1);
WS.Cells[1, 1] = txtTATW.Text;
WB.Save();
}
catch (Exception ex)
{
MessageBox.Show("Write Excel: " + ex.Message);
}
finally
{
GC.Collect();
GC.WaitForPendingFinalizers();
releaseObject(WS);
releaseObject(WBs);
releaseObject(WB);
releaseObject(XlsB);
WB.Close(true, lblPath.Text, misValue);
Xls.Quit();
releaseObject(Xls);
}
}
Finally the release method: 最后释放方法:
private void releaseObject(object obj)
{
try
{
System.Runtime.InteropServices.Marshal.FinalReleaseComObject(obj);
obj = null;
}
catch (Exception ex)
{
obj = null;
MessageBox.Show("Unable to release the Object " + ex.ToString());
}
}
Some of the data is carried over from a different form, which is not visible here, but everything important should be listed! 某些数据是通过不同的形式传递的,在这里看不到,但是所有重要的信息都应该列出!
It basically just pulls data from a textbox into a particular cell. 它基本上只是将数据从文本框中提取到特定的单元格中。 For now, i'm testing it with only once cell. 现在,我仅用一个单元进行测试。 Here's to hoping a second pair of eyes can help me find a solution. 希望第二只眼睛可以帮助我找到解决方案。
I moved the line ~WB.Close()~ before the release ~releaseObject(WB)~ The code changes cell[1,1] with some text. 我将行〜WB.Close()〜移到了发行版〜releaseObject(WB)〜之前,代码用一些文本更改了cell [1,1]。 I changed the path and the text from the form, but the excel part saves properly. 我从表单更改了路径和文本,但是excel部分保存正确。 Hope this helps. 希望这可以帮助。
