突然之间,这段代码停止了输出 Excel 文件。它正在将 DataTable dtOutput 转换为 Excel 文件:
if (dtOutput.Rows.Count > 0)
{
DataView dv = dtOutput.DefaultView;
dv.Sort = "Outage Start Time";
dtOutput = dv.ToTable();
// Populates a column of the table
dtOutput = addIncidentCounts(dtOutput);
Microsoft.Office.Interop.Excel.Application xlApp = new Microsoft.Office.Interop.Excel.Application();
Workbook wb = xlApp.Workbooks.Add(XlWBATemplate.xlWBATWorksheet);
Worksheet ws = (Worksheet)wb.Worksheets[1];
ws.Name = "Retail Network Tracking Log";
int col = 1;
foreach (DataColumn column in dtOutput.Columns)
{
ws.Cells[1, col].Value2 = column.ColumnName;
col++;
}
for (int i = 0; i < dtOutput.Rows.Count; i++)
{
for (int j = 0; j < dtOutput.Columns.Count; j++)
{
ws.Cells[i + 2, j + 1].Value2 = dtOutput.Rows[i][j];
}
}
foreach (Range range in ws.UsedRange.Columns)
{
range.HorizontalAlignment = XlHAlign.xlHAlignLeft;
range.Columns.AutoFit();
}
Range rangeE = ws.get_Range("E:E", Type.Missing);
rangeE.NumberFormat = "d-mmm-yyyy hh:mm:ss";
Range rangeF = ws.get_Range("F:F", Type.Missing);
rangeF.NumberFormat = "d-mmm-yyyy hh:mm:ss";
wb.Close(false, false, Type.Missing);
xlApp.Quit();
Marshal.ReleaseComObject(wb);
Marshal.ReleaseComObject(xlApp);
this.Close();
}
它已经完美运行了数周。我没有对其进行任何更改。我重新启动了VS,重新启动了计算机,最后重新安装了VS,但我仍然没有得到任何输出。我也通过调试器运行了它,代码肯定正在执行并获得所有正确的值。我难住了。
