文件导入我的WPF应用程序并查看它。我将文档转换为.xps,然后加载。然后我调用GetFixedDocumentSequence()
,在那里我得到了这个异常
XamlParseException:
{“UnicodeString属性未包含足够的字符,无法
与Indexes属性“”的内容相对应
这是我的密码:
private void LoadData()
{
string xpsPath = ViewDocumentViewer("D:\\test.xlsx");
DisplayXPSFile(xpsPath);
}
private string ViewDocumentViewer(string path)
{
try
{
string xpsPath;
var excelApp = new Microsoft.Office.Interop.Excel.Application();
excelApp.DisplayAlerts = false;
excelApp.Visible = false;
Microsoft.Office.Interop.Excel.Workbook excelWorkbook = excelApp.Workbooks.Open(path);
xpsPath = ExportXPS(excelWorkbook, path);
excelWorkbook.Close(false, null, null);
excelApp.Quit();
Marshal.ReleaseComObject(excelApp);
excelApp = null;
return xpsPath;
}
catch
{
}
return string.Empty;
}
string ExportXPS(Microsoft.Office.Interop.Excel.Workbook excelWorkbook, string path)
{
string xpsFileName;
xpsFileName = (new DirectoryInfo(path)).FullName;
xpsFileName = xpsFileName.Replace(new FileInfo(path).Extension, "") + ".xps";
excelWorkbook.ExportAsFixedFormat(XlFixedFormatType.xlTypeXPS,
Filename: xpsFileName,
OpenAfterPublish: false);
return xpsFileName;
}
void DisplayXPSFile(string xpsFileName)
{
XpsDocument xpsPackage = new XpsDocument(xpsFileName, FileAccess.Read, CompressionOption.NotCompressed);
FixedDocumentSequence fixedDocumentSequence = xpsPackage.GetFixedDocumentSequence();
DocView.Document = fixedDocumentSequence;
}
看起来Excel转换到XPS时出现了问题。 这通常与字形或字体问题有关。 您可以打开XPS文件(我在Visual Studio上使用此扩展名:)以查看问题的来源。导航到生成错误的页面并找到包含问题的图示符

由于use使用Excel Interop生成XPS,您几乎无法控制转换过程,因此我建议您查看Excel文档中使用的字体。
也许使用的字体有问题
