c#调用vb 的dll，参数类型问题
vb编写的dll的函数原型为
Public Declare Function SetEditText(ByVal FCaption As String, ByVal Times As Long, ByVal dwspeed As Long) As Long
c#调用方式

[DllImport("xxx.dll")]
private static extern int SetEditText(string str, int times, int speed);

运行总是乱码，比如我传入“你好”，变成“e”，
求高手指点这里应该怎么写，非常感谢。

[解决办法]
COM
COM
VB的DLL是COM


[解决办法]
vb的string是unicode编码吗
[解决办法]
System.Text.Encoding.GetEncoding("GB2312")
编码处理下吧
