C# 导出EXCEL报错

初步判断可能原因为

1。WPS相关冲突

2。系统更新冲突

部分客户端重装MICROSOFT OFFICE后可以正常使用。

部分客户端卸载WPS OFFICE后重装MICROSOFT OFFICE后可以正常使用。

仍有部分客户端以上方法都无效。

临时解决方案，采用第三方组件NPOI

public static void DataToExcelByNPOI(DataGridView dgv)
{
try
{
int rowCount = dgv.Rows.Count;
int colCount = dgv.Columns.Count;

//行数列数必须大于0
if (rowCount <= 0 || colCount <= 0)
{
MessageBox.Show("没有数据可供导出！", "提示信息", MessageBoxButtons.OK, MessageBoxIcon.Warning);
return;
}
NPOI.HSSF.UserModel.HSSFWorkbook workbook = new NPOI.HSSF.UserModel.HSSFWorkbook();
MemoryStream ms = new MemoryStream();

NPOI.SS.UserModel.ISheet sheet = workbook.CreateSheet("Sheet1");

try
{
//填入表头
NPOI.SS.UserModel.IRow dataHeadRow = sheet.CreateRow(0);
for (int j = 0; j < colCount; j++)
{
if (dgv.Columns[j].Visible && dgv.Columns[j].HeaderText != "")
{
NPOI.SS.UserModel.ICell cell = dataHeadRow.CreateCell(j);
cell.SetCellValue(dgv.Columns[j].HeaderText.ToString());
}
}
//填入明细
for (int i = 0; i < rowCount; i++)
{
NPOI.SS.UserModel.IRow dataRow = sheet.CreateRow(i+1);
for (int j = 0; j < colCount; j++)
{
if (dgv.Columns[j].Visible && dgv.Rows[i].Cells[j].Value != null)
{
NPOI.SS.UserModel.ICell cell = dataRow.CreateCell(j);
cell.SetCellValue(dgv.Rows[i].Cells[j].Value.ToString());
}
}
}

workbook.Write(ms);
SaveFileDialog sfd = new SaveFileDialog();

sfd.Filter = "Excel 97-2003工作薄(*.xls)|*.xls";
sfd.DefaultExt = ".xls";
sfd.RestoreDirectory = true;
sfd.OverwritePrompt = true;
sfd.Title = "保存文件";
if (DialogResult.OK != sfd.ShowDialog())
{
return;
}

string strFileName = sfd.FileName;

if (System.IO.File.Exists(strFileName))
{
System.IO.File.Delete(strFileName);
}
FileStream file = new FileStream(strFileName, FileMode.Create);
workbook.Write(file);
file.Close();
MessageBox.Show("保存EXCE成功", "提示信息", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
catch (Exception)
{
throw;
}
finally
{
workbook = null;
ms.Close();
ms.Dispose();
}
}
catch (Exception err)
{
MessageBox.Show(err.Message, "提示信息", MessageBoxButtons.OK, MessageBoxIcon.Warning);
}
}
