Question

我想将数据导出到格式化的XLS，但我似乎有某种限制问题。它会导出一些数据集，有些则不会我已经浏览了生成的XML并对大部分行进行了评论，然后逐个取消它们，直到文档打开为止。我知道行和列的限制，但结果文档远远没有在Excel之前打开。我说的是当超过34个excel行（大约500个格式化XML行）时失败。

这是我的完整导出代码：

private void GenerateConfigReport(HttpContext context)
{
    GIS34PortalService client = new GIS34PortalService();
    DataTable features = client.GetFeatures(objectId, "id");
    string filename = "ConfigRapport";            

    #region header

    StringBuilder header = new StringBuilder();
    header.AppendLine("<?xml version=\"1.0\" encoding=\"utf-8\"?>");
    header.AppendLine("<?mso-application progid=\"Excel.Sheet\"?>");
    header.AppendLine("<Workbook xmlns=\"urn:schemas-microsoft-com:office:spreadsheet\" xmlns:o=\"urn:schemas-microsoft-com:office:office\" xmlns:x=\"urn:schemas-microsoft-com:office:excel\" xmlns:ss=\"urn:schemas-microsoft-com:office:spreadsheet\" xmlns:html=\"http://www.w3.org/TR/REC-html40\">");
    header.AppendLine(" <DocumentProperties xmlns=\"urn:schemas-microsoft-com:office:office\">");
    header.AppendLine("  <Author>Amit Bracha</Author>");
    header.AppendLine("  <LastAuthor>Amit Bracha</LastAuthor>");

    header.AppendLine("  <LastSaved>" + DateTime.Now + "</LastSaved>");

有没有人知道为什么Excel不会打开这个文件？

Answer 1

我不认为这是一个限制，因为我们知道Excel不限于这么少的行数。几乎可以肯定的是，特殊字符的数据/转义问题......使用AppendLine添加行的方式并不安全......不存在'＆lt;'或者数据中的其他无效XML字符？

我建议你使用一个合适的XLS组件，以便解决所有这些问题...那里有很多免费的，开源的和商业的。

Answer 2

ExpandedRowCount是你的问题。显然它与实际行数不匹配。

我删除了它，它打开就好了。

更好的选择是输出实际的行数。
