【问题描述】：

我在 sql 中有几个表，我想在单击表单按钮后将它们导出为 PDF 文件 有谁知道我该怎么做？

当我将表格从 SQL 导出到 Excel 时，我有这个代码：

protected void insertBTN(object sender, EventArgs e)

string conString = @"Data Source =XXXX; Initial Catalog=XXXX;     Persist Security     Info=True;User ID=XXXX; Password=XXXX";SqlConnection sqlCon     = new     SqlConnection(conString);
sqlCon.Open();

SqlDataAdapter da = new SqlDataAdapter("SELECT * from InjuryScenario", sqlCon);
System.Data.DataTable dtMainSQLData = new System.Data.DataTable();
da.Fill(dtMainSQLData);
DataColumnCollection dcCollection = dtMainSQLData.Columns;
// Export Data into EXCEL Sheet
Microsoft.Office.Interop.Excel.ApplicationClass ExcelApp = new                                            
Microsoft.Office.Interop.Excel.ApplicationClass();
ExcelApp.Application.Workbooks.Add(Type.Missing);
// ExcelApp.Cells.CopyFromRecordset(objRS);
for (int i = 1; i < dtMainSQLData.Rows.Count + 2; i++)

    for (int j = 1; j < dtMainSQLData.Columns.Count + 1; j++)
    
        if (i == 1)
        
            ExcelApp.Cells[i, j] = dcCollection[j - 1].ToString();
        
        else
            ExcelApp.Cells[i, j] = dtMainSQLData.Rows[i - 2][j - 1].ToString();
    

ExcelApp.ActiveWorkbook.SaveCopyAs("C:\\Users\\Mor Shivek\\Desktop\\test.xls");
ExcelApp.ActiveWorkbook.Saved = true;
ExcelApp.Quit();

【参考方案1】：

“导出为 PDF”是什么意思？使用上面的excel导出然后使用PDF打印机发送文件的打印命令不是最简单的方法吗？ 如果您想以本机方式创建 PDF，您很可能会花一些精力来布局文档。

【讨论】：

我想选择以 PDF 格式保存文件

那么就这样吧！？ ***.com/questions/13233359/…

他的问题是另一笔交易。我只是说函数 openWorkBook.ExportAsFixedFormat(ExcelApp.XlFixedFormatType.xlTypePDF, pdfPathName);

我看不懂怎么写，你能解释一下吗？谢谢

你有什么不明白的？而不是 .SaveCopyAs() 您使用 .ExportAsFixedFormat()
