  AxMapControl1.AddLayer(my_raster);
  }
--------------------------------------------------
public void Delete_map()

推荐答案

路径"应为有效路径，例如"c:\ filename.ext"等.如果它是变量，则应执行此操作:

"path" should be a valid path like "c:\filename.ext" etc. if it is a variable the you should be doing :

System.IO.File.delete(path);

我举了一个例子...路径有效，但仍然无法删除图像....我使用了Dispose()方法，但结果仍然相同:(

I gave an example... Path is valid but still I cannot delete image.... I used Dispose() method but still same the result :(

有人可以帮助我:(非常重要.
