无法获得正确的图像路径 [英] Not get correct image path

问题描述

在我的窗口应用程序中，单击时更改按钮的图像.我使用SaveFileDialog将数据保存在文本文件中.当我单击按钮将数据保存到文本文件中后，它会很好地产生如下错误:找不到文件异常."如果找不到文件，则在将数据保存到文本文件之前，我不会更改图像.我在按钮单击事件中使用此代码进行图像更改:

In my window application I change image of button when click. I save data in text file using SaveFileDialog. After save data in text file when I click my button it well generate error like this:"File not found Exception was caught". If file not found then I will not change image before save data in text file. I use this code at button click event for image change:

btn_Stop.Image = Bitmap.FromFile("..\\Image\\btn_Stop.Image.jpg");
btn_Start.Image = Bitmap.FromFile("..\\Image\\btn_Start.red.jpg");

推荐答案

您真的不想在这里使用相对路径-就是这样:相对于当前位置.

如果将这些图像存储在应用程序所在位置下的目录中，请绝对指定该文件夹:

You really do not want to use a relative path here - it is just that: relative to the current location.

If you store these images in a directory below the location where the application resides, then specify that folder absolutely:

btn_Stop.Image = Bitmap.FromFile(Application.StartupPath + "\\Image\\btn_Stop.Image.jpg");
btn_Start.Image = Bitmap.FromFile(Application.StartupPath + "\\Image\\btn_Start.red.jpg");

除了解决方案1，

In addition to the Solution 1,

btn_Stop.Image = Bitmap.FromFile(Path.Combine(Application.StartupPath , "Image\\btn_Stop.Image.jpg"));
btn_Start.Image = Bitmap.FromFile(Path.Combine(Application.StartupPath , "Image\\btn_Start.red.jpg"));

希望对您有所帮助:)
