“System.ArgumentException”发生在 System.Drawing.dll 中

Question

我收到此错误System.ArgumentException: 参数无效。在 System.Drawing.Bitmap..ctor(String filename) at PressRoom.ImageHandler.getResizedImage(String path, Int32 width, Int32 height)在线byte[] getResizedImage(String path, int width, int height){        if (path!=null)        {            Bitmap imgIn = new Bitmap(path); // exception is thrown            double y = imgIn.Height;            double x = imgIn.Width;}我该如何处理这个异常？

Answer 1

你为什么不用 try-catch 包围你的代码？当路径无效时通常会抛出异常，检查两次该文件是否存在或路径格式正确

Bitmap imgIn;

try

{

    imgIn = new Bitmap(path);

    double y = imgIn.Height;

    double x = imgIn.Width;

}

catch (ArgumentException e)

{

    Console.WriteLine(e.Message);

    return null;

}
