c#-将行设置为在打印时在顶部重复-打开XML和Excel
作者：互联网
我正在尝试获取xlsx文件的前4行,以便在打印时在每页顶部重复.我正在使用Open XML SDK来完成此任务.
我的文件由SSRS执行Web服务作为文件流生成.然后,在将文件交付给用户之前,我需要修改几个布局和页面设置(页边距,页面大小,缩放比例等),因为我的用户几乎没有Excel敏锐度.我需要调整的所有其他设置都可以正常工作,因此我从该示例中删除了所有这些代码.
当尝试使用下面的代码设置重复的页眉时,它会正确执行.但是,当我在执行代码后尝试打开文件时,我收到了损坏的文件消息,并且无法打开.
知道我在这里做错了吗？！这让我疯狂！
using (SpreadsheetDocument xl = SpreadsheetDocument.Open("C:\\" + filename, true))
{
WorkbookPart wbp = xl.WorkbookPart;
//-----------------------------------------
// repeat rows at top when printing
//-----------------------------------------
DefinedNames dn = new DefinedNames();
wbp.Workbook.Append(dn);
wbp.Workbook.Save();
DefinedNames definedNames = wbp.Workbook.Descendants<DefinedNames>().FirstOrDefault();
DefinedName n1 = new DefinedName() { Name = "_xlnm.Print_Titles", LocalSheetId = (UInt32Value)0U };
n1.Text = "alpha_sort_nc!$1:$4";
definedNames.Append(n1);
wbp.Workbook.Save();
xl.Close();
}
解决方法:
更新：
@Duncan-在您发表评论后,我尝试找出文件损坏的根本原因.原来是SpreadsheetPinterSettings是文档中的二进制数据.甚至将DefinedName _xlnm.Print_Titles添加到电子表格；在“打印/打印预览”期间它没有任何作用.
似乎用于处理电子表格打印机设置的Open XML方法没有帮助.
反映来自Open XML SDK生产力工具的代码：在MS Excel中手动创建的打印标题
// Adds child parts and generates content of the specified part.
public void CreateSpreadsheetPrinterSettingsPart(SpreadsheetPrinterSettingsPart part)
{
GeneratePartContent(part);
}
// Generates content of part.
private void GeneratePartContent(SpreadsheetPrinterSettingsPart part)
{
System.IO.Stream data = GetBinaryDataStream(partData);
part.FeedData(data);
data.Close();
}

备用方法[我不确定,您是否有兴趣:)]：由于二进制数据部分,使用Interop的代码段相同.完美的作品！
Excel.Application xlApp = new Excel.Application();
Excel._Workbook xlWorkbook = xlApp.Workbooks.Open(@"C:/Users/jeeva/sample-excel-files/SampleExcel.xlsx");
Excel._Worksheet xlWorksheet = xlWorkbook.Sheets[1];
xlWorksheet.PageSetup.PrintTitleRows = "$1:$1";
xlWorkbook.Save();
xlWorkbook.Close();
前一个：
这三行不是必要的.
DefinedNames dn = new DefinedNames();
wbp.Workbook.Append(dn);
wbp.Workbook.Save();
要设置打印标题,DefinedName Text的格式应为“ Worksheet_name！Row_Range或Column_Range”.
例如：行范围：Worksheet1！$1：$1和列范围：Worksheet1！$A：$A
using (SpreadsheetDocument xl = SpreadsheetDocument.Open(@"C:/Users/jeeva/sample-excel-files/SampleExcel.xlsx", true))
{
WorkbookPart wbp = xl.WorkbookPart;
// Input for this program
string name = "_xlnm.Print_Titles";
