我有 6个错误
有关'FaceStat.Form1.AsmSearchDll的最佳重载的方法匹配(OUT INT,出INT [],字符串,字符串,INT,INT,INT,字符串,字符串)'有一些无效参数
4的说法无法从转换'System.IntPtr 到串
为最佳重载方法匹配'cvlib.cvPolyLine(CvArr,CvPoint [],INT [],INT,INT,CvScalar) 有一些无效参数
参数2不能从转换'INT []'到'CvPoint []
参数3无法从'诠释'转换为'廉政[]
参数5:无法从布尔转换为 INT
感谢
的C ++ DLL

You didn't specified cvPolyLine... so I can't check arguments. Anyway... you are just passing wrong value types to your method. As simple as this.
