VB.NET下有没有什么合适的dll申明工具？该怎么处理

    Public Structure SHFILEOPSTRUCT
        Dim hwnd As IntPtr
        Dim wFunc As Integer
        Dim pFrom As String
        Dim pTo As String
        Dim fFlags As Short
        Dim fAnyOperationsAborted As Integer
        Dim hNameMappings As IntPtr
        Dim lpszProgressTitle As String
    End Structure

    Public Declare Function SHFileOperation Lib "shell32.dll" Alias "SHFileOperationA" (ByRef lpFileOp As SHFILEOPSTRUCT) As Integer
