C#如何读取共享文件夹
请问一下,公司服务器上有个共享文件夹,我在上面专门创建了一个用户cUser,密码123456。服务器地址是192.168.1.100,文件夹名称《新建文件夹》,里面有一个excel文件《生产系统.xls》。
我在服务器上设置了该cUser用户对共享文件夹有只读权限。
请问我用c#如何去连接这个共享文件夹里面的excel文件。
读取excel时需要指定路径。请问这个路径应该怎么获取?
非常感谢

使用这个类来访问网络共享的文件夹
public class IdentityScope : IDisposable

[DllImport("kernel32.dll", CharSet = CharSet.Auto)]
