VB.Net中动态调用dll解决思路

    Declare Function LoadLibrary Lib "kernel32" Alias _
          "LoadLibraryA" (ByVal lpLibFileName As String) As Integer
    Declare Function FreeLibrary Lib "kernel32" Alias _
          "FreeLibrary" (ByVal hLibModule As Integer) As Integer
    Declare Function GetProcAddress Lib "kernel32" Alias _
          "GetProcAddress" (ByVal hModule As Integer, _
          ByVal lpProcName As String) As Integer
    Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim hLib As Integer = LoadLibrary("CMPPAPI.dll")
        Dim apiaddress As Integer = GetProcAddress(hLib, _
                        "InitCMPPAPI")
    End Sub

探讨

dim objAssembly As [Assembly] = [Assembly].LoadFrom(XXX.dll)

Dim objType As Type = objAssembly.GetType(函数所在的类)

Dim objAdapter As Object = Activator.CreateInstance(objType)

Dim objMethodInfo As System.Reflection.MethodInfo = objType.GetMethod(函数名)

Dim objResult As Object = objMethodInfo.Invoke(objAdapter, 参数配列)
