C#访问共享文件夹问题

我想访问一个共享文件夹,于是我就直接写了一条代码

System.Diagnostics.Process.Start(@"\\192.168.0.2\文件夹");

我想判断是否成功连接共享文件夹,应该怎么写?

调用windows的API吧

using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;

namespace WindowsApplication1

ERROR_BAD_NETPATH = 53,
ERROR_NO_NETWORK = 1222,
ERROR_INVALID_HANDLE_STATE = 1609,

RESOURCEUSAGE_CONTAINER = 2,
RESOURCEUSAGE_NOLOCALDEVICE = 4,
RESOURCEUSAGE_SIBLING = 8,
RESOURCEUSAGE_ATTACHED = 16,
RESOURCEUSAGE_ALL = (RESOURCEUSAGE_CONNECTABLE | RESOURCEUSAGE_CONTAINER | RESOURCEUSAGE_ATTACHED),
}

public enum RESOURCE_DISPLAYTYPE
{
RESOURCEDISPLAYTYPE_GENERIC = 0,
RESOURCEDISPLAYTYPE_DOMAIN = 1,
RESOURCEDISPLAYTYPE_SERVER = 2,
RESOURCEDISPLAYTYPE_SHARE = 3,
RESOURCEDISPLAYTYPE_FILE = 4,
RESOURCEDISPLAYTYPE_GROUP = 5,
RESOURCEDISPLAYTYPE_NETWORK = 6,
RESOURCEDISPLAYTYPE_ROOT = 7,
RESOURCEDISPLAYTYPE_SHAREADMIN = 8,
RESOURCEDISPLAYTYPE_DIRECTORY = 9,
RESOURCEDISPLAYTYPE_TREE = 10,
RESOURCEDISPLAYTYPE_NDSCONTAINER = 11
}

[StructLayout(LayoutKind.Sequential)]
public struct NETRESOURCE
{
public RESOURCE_SCOPE dwScope;
public RESOURCE_TYPE dwType;
public RESOURCE_DISPLAYTYPE dwDisplayType;
public RESOURCE_USAGE dwUsage;

[MarshalAs(UnmanagedType.LPStr)]

}
