現在的項目中遇到一個棘手的問題，用了很長的時間才找到解決的辦法，所以把解決方案展示出來。

需求：把一個二進制字節數組（byte[]）存到moss文檔庫中
環境：虛機和測試機都是(moss2007+vs2005)，并且虛機自己作為域控，而測試機是域里的一臺機器
實現：
? 保存：public bool SaveData(string fileurl, byte[] bits)
??????? {
??????????? bool save = false;
??????????? using (SPSite site = new SPSite(fileurl))
??????????? using (SPWeb web = site.OpenWeb())
??????????? {
??????????????? SPFile file = web.GetFile(fileurl);
??????????????? file.SaveBinary(bits);
??????????????? save = true;
??????????? }
??????????? return save;
??????? }
獲取的二進制數組：
??????? public byte[] GetWorkbookBits(WorkbookType type, string SeeionID)
??????? {
??????????? try
??????????? {
??????????????? ExcelService s = new ExcelService();
??????????????? Status[] status;
??????????????? s.Credentials = CredentialCache.DefaultCredentials;

??????????????? byte[] bits = s.GetWorkbook(SeeionID, type, out status);
??????????????? return bits;
??????????? }
??????????? catch (Exception soapEx)
??????????? {

??????????????? throw new ApplicationException("The session has timed out.");

??????????? }
??????? }
效果：虛機上保存成功，但是到測試機上生成的excel2007文件在打開時（下載到本地）有如下的錯誤：excel found unreadable content in <filename>,do you want to recover the contents of this workbook
我的解決：
1、比較web.config配置-----沒有區別
2、比較office版本，開始的時候虛機是12.0.4518.1014，后來和服務器一樣12.0.6300.5000
3、參考一下頁面http://blogs.msdn.com/cumgranosalis/archive/2007/08/03/excel-found-unreadable-content-in-workbook-do-you-want-to-recover-the-contents-of-this-workbook.aspx

最終的解決辦法很簡單是file.SaveBinary(bits);方法中file文件由原來的“.xlsx”改成“.xlsb”格式文件。
