c＃netapi32 netuseadd console app OK winform NG

Question

我在控制台应用程序中使用以下声明＆amp;一个winforms应用程序。两者都是3.5框架。

    [DllImport("NetApi32.dll", SetLastError = true, CharSet = CharSet.Unicode)]
    internal static extern NET_API_STATUS NetUseAdd(
        LPWSTR UncServerName,
        DWORD Level,
        ref USE_INFO_2 Buf,
        out DWORD ParmError);

控制台应用程序正常，winform应用程序错误：

无法在DLL'NetApi32.dll'中找到名为'NetUseAdd'的入口点

我已经在网上搜索过了想出了下面的声明。这个1给winform app提供了相同的错误。

    [DllImport("NetApi32.dll", 
        SetLastError = true, 
        CharSet = CharSet.Unicode
        )]
    public static extern uint NetUseAdd(
         string UncServerName,
         UInt32 Level,
         USE_INFO_2 Buf,
         out UInt32 ParmError
        );

    [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Unicode)]
    public struct USE_INFO_2
    {
        public string ui2_local;
        public string ui2_remote;
        public string ui2_password;
        public UInt32 ui2_status;
        public UInt32 ui2_asg_type;
        public UInt32 ui2_refcount;
        public UInt32 ui2_usecount;
        public string ui2_username;
        public string ui2_domainname;
    }

我运行了dumpbin / export＆amp; NetUseAdd就在那里。

非常感谢所有帮助。
