我开发了一个 C# windows 应用程序。它从 excel 文件中读取数据并写入新的 excel 工作簿。为此 WinApp 创建了一个 EXE。如果我从本地机器运行应用程序或 EXE，它工作正常。将新的 Excel 保存到我的 C 盘。我将 msi 和 exe 文件复制到另一台机器并安装了 msi。
从这些机器运行 exe 时出现以下错误。“保存文件时出错”。
注意：- 读取文件没有问题。我通过浏览不同类型的文件（如 .jpg、.doc 等）来检查它，在这种情况下，它要求我们浏览相关文件。
我的代码：
existingFileToWrite1 = @"C:\\LeadOwners-IN";
using (packageToWrite1 = new ExcelPackage(existingFileToWrite1))
{
worksheetToWrite.Cells["A1"].Value = "Lead Owners Mail";
worksheetToWrite.Cells["B1"].Value = "TotalLeads-" + sRegion.Trim();
worksheetToWrite.Cells["C1"].Value = sLInfo + "1-" + sRegion.Trim();
worksheetToWrite.Cells["D1"].Value = sLInfo + "2-" + sRegion.Trim();
worksheetToWrite.Cells["E1"].Value = sLInfo + "3-" + sRegion.Trim();
worksheetToWrite.Cells["F1"].Value = sLInfo + "4-" + sRegion.Trim();
worksheetToWrite.Cells["G1"].Value = sLInfo + "5-" + sRegion.Trim();
worksheetToWrite.Cells["H1"].Value = sLInfo + "6-" + sRegion.Trim();
worksheetToWrite.Cells["I1"].Value = sLInfo + "7-" + sRegion.Trim();
worksheetToWrite.Cells["J1"].Value = sLInfo + "8-" + sRegion.Trim();
worksheetToWrite.Cells["K1"].Value = sLInfo + "9-" + sRegion.Trim();
worksheetToWrite.Cells["L1"].Value = sLInfo + "10-" + sRegion.Trim();
worksheetToWrite.Cells["C" + Iteration1].Value = sFull1.Substring(0, sFull1.Length);
worksheetToWrite.Cells["D" + Iteration1].Value = string.Empty;
worksheetToWrite.Cells["E" + Iteration1].Value = string.Empty;
worksheetToWrite.Cells["F" + Iteration1].Value = string.Empty;
worksheetToWrite.Cells["G" + Iteration1].Value = string.Empty;
worksheetToWrite.Cells["H" + Iteration1].Value = string.Empty;
worksheetToWrite.Cells["I" + Iteration1].Value = string.Empty;
worksheetToWrite.Cells["J" + Iteration1].Value = string.Empty;
worksheetToWrite.Cells["K" + Iteration1].Value = string.Empty;
worksheetToWrite.Cells["L" + Iteration1].Value = string.Empty;
packageToWrite1.Save();
}
