C# Signature:

    /// <summary>
    /// The NetDfsEnum function enumerates all the Distributed File System (Dfs) links in the named Dfs root. The function returns information about the Dfs links based on information specified by the Level parameter.
    /// </summary>
    /// <param name="DfsName">[in] Pointer to a string that specifies the name of the DFS root or a DFS link. </param>
    /// <param name="Level">[in] Specifies the information level of the request. This parameter can be one of the following values. </param>
    /// <param name="PrefMaxLen">[in] Specifies the preferred maximum number of bytes that should be returned by this enumeration function call in the information structure buffer. If this parameter is MAX_PREFERRED_LENGTH, the function allocates the amount of memory required for the data. For more information, see the following Remarks section. This parameter is ignored if you specify level 200 or level 300.</param>
    /// <param name="Buffer">[out] Pointer to the address of a buffer that receives the requested information structures. The format of this data depends on the value of the Level parameter. This buffer is allocated by the system and must be freed using the NetApiBufferFree function. </param>
    /// <param name="EntriesRead">[out] Pointer to a value that receives the actual enumerated DFS link count. </param>
    /// <param name="ResumeHandle">[in, out] Pointer to a value that contains a handle which is used to continue the enumeration. The handle should be zero on the first call and left unchanged for subsequent calls. For more information, see the following Remarks section. Windows Server 2003:  If ResumeHandle is NULL, then no resume handle is stored.</param>
    /// <returns>If the function succeeds, the return value is NERR_Success. If no more entries are available to be enumerated, the return value is ERROR_NO_MORE_ITEMS. If the function fails, the return value is a system error code</returns>
