首先是:

• 服务器: 乌班图10.04服务器

  mongod ——————

  db edition v1.2.2, pdfile edition 4.5

• 客户:Windows 7 64bit, VS2010 app, 采用C#正式司机诉1.3。

I m trying to store a png image in the mongoDB using the GridFS. My code looks like this:

var GridFSInfo = DB.GridFS.Upload(TextureFileName, TextureFileName);

Running this code I get the following exception

An unhandled exception of type  MongoDB.Driver.GridFS.MongoGridFSException  occurred in MongoDB.Driver.dll 

Additional information: Upload client and server MD5 hashes are not equal.

I have tried to find info on this error, but I seem to be the only person having trouble with this :(

服务器记录没有出现任何错误,我发现:

This looks to me like the file transfer is initiated but then something goes wrong. I triplechecked that the file exists. I used the mongofiles command line utility to see if the GridFS works and everything is fine there, upload of files is no problem. My app also works fine if I do not make the GridFS upload and only use standard BSON document manipulation. I can insert, search, delete fine, so the connection to the server works.

我现在要问一下这究竟是什么原因。 我感谢任何方面。
