使用方法
1 MongoFileBll tl = new MongoFileBll("mongodb://127.0.0.1:27017/chzhaotest");
2 string folder = @"D:\Wisdombud\2016\20160324_Wisdombud.Mongo\SourceCode\Wisdombud.Mongo.Sample\bin\Debug";
3 DirectoryInfo di = new DirectoryInfo(folder);
4 foreach (var file in di.GetFiles())
5 {
6 tl.UploadFile(file.FullName, Guid.NewGuid().ToString());
7 }
8 var aaa = tl.FindAll();
9 foreach (var inst in aaa)
10 {
11 Console.WriteLine(inst.Name);
12 }
