打开记忆XML字符串作为一个Excel工作簿，但不保存使用Windows窗体C＃ [英] Open in memory XML string as an Excel workbook without saving using windows Forms C#

问题描述

我有一个Excel字符串（我建）内存;代码看起来是这样的：

I have an excel string (which I built) in memory; the code looks something like this:

public static void exportToExcel()
        {
            const string startExcelXML = "<xml version>\r\n<Workbook " +
                  "xmlns=\"urn:schemas-microsoft-com:office:spreadsheet\"\r\n"
+
                  " xmlns:o=\"urn:schemas-microsoft-com:office:office\"\r\n " +
                  "xmlns:x=\"urn:schemas-    microsoft-com:office:" +
                  "excel\"\r\n xmlns:ss=\"urn:schemas-microsoft-com:"
+
                  "office:spreadsheet\">\r\n <Styles>\r\n " +
                  "<Style ss:ID=\"Default\" ss:Name=\"Normal\">\r\n " +
                  "<Alignment ss:Vertical=\"Bottom\"/>\r\n <Borders/>" +
                  "\r\n <Font/>\r\n <Interior/>\r\n <NumberFormat/>" +
                  "\r\n <Protection/>\r\n </Style>\r\n " +
                  "<Style ss:ID=\"BoldColumn\">\r\n <Font " +
                  "x:Family=\"Swiss\" ss:Bold=\"1\"/>\r\n </Style>\r\n " +
                  "<Style     ss:ID=\"StringLiteral\">\r\n <NumberFormat" +
                  " ss:Format=\"@\"/>\r\n </Style>\r\n <Style " +
                  "ss:ID=\"Decimal\">\r\n <NumberFormat/>\r\n </Style>\r\n " +
                  "<Style ss:ID=\"Integer\">\r\n <NumberFormat "
+
                  "ss:Format=\"0\"/>\r\n </Style>\r\n <Style " +
                  "ss:ID=\"DateLiteral\">\r\n <NumberFormat " +
                  "ss:Format=\"dd/mm/yyyy;@\"/>\r\n </Style>\r\n " +
                  "</Styles>\r\n ";
            const string endExcelXML = "</Workbook>";

            int sheetCount = 1;
            StringBuilder sb = new StringBuilder();

            sb.Append(startExcelXML);
            sb.Append("<Worksheet ss:Name=\"Sheet" + sheetCount + "\">");
            sb.Append("<Table>");
            sb.Append("<Row>");
            sb.Append("<Cell ss:StyleID=\"BoldColumn\"><Data ss:Type=\"String\">");
            sb.Append("Home country");
            sb.Append("</Data></Cell>");
            sb.Append("<Cell ss:StyleID=\"BoldColumn\"><Data ss:Type=\"String\">");
            sb.Append("Expatriation Type");
            sb.Append("</Data></Cell>");
            sb.Append("</Row>");
            sb.Append("<Row>");
     sb.Append("<Cell ss:StyleID=\"StringLiteral\">" +
      "<Data ss:Type=\"String\">");
     sb.Append("Singapore");
     sb.Append("</Data></Cell>");
     sb.Append("<Cell ss:StyleID=\"StringLiteral\">" +
      "<Data ss:Type=\"String\">");
     sb.Append("Benchmark");
     sb.Append("</Data></Cell>");
            sb.Append("</Row>");
            sb.Append("</Table>");
            sb.Append(" </Worksheet>");
            sb.Append(endExcelXML);
        }

我能够打开该文件为excel表只有当我保存体力文件;但是否有任何其他方式只需打开从内存中Excel工作表的XML字符串？

I able to open the file as excel sheet only if I save the file physically; but is there any other way to just open the xml string from the memory as excel sheet?

推荐答案

我想你会需要的是某种类型的内存映射文件执行。

I think what you'll need is a memory mapped file implementation of some kind.

我相信，虽然，.NET 4.0将内置于 MemoryMappedFile 的支持。

I believe, though, that .NET 4.0 will have built-in MemoryMappedFile support.

您可能能够找到使用搜索引擎等.NET实现。

You may be able to find other .net implementations using a search engine.
