从路径名中获取Image对象

Question

给定路径和文件名，我如何获取Image对象：

Image image = ...(filename)

Answer 1

您想要在Image类上调用静态FromFile方法 。

Answer 2

Another alternative is to use a Bitmap object (which inherits from Image) like so:

Bitmap bitmap = new Bitmap(imagePath);

(This works for all image formats, not just *.bmp as the name might imply.)

Answer 3

// Get original filename with extention
            string filenameWithPath = "C:\pictures\peanutbutterjellytime.jpg;
            filename = System.IO.Path.GetFileName(filenameWithPath); 

Answer 4

If you're playing with images in memory, I've found that bobpowell.net has a GREAT site for GDI work in C#.

No.. I'm not related to, associated with or hired by Bob Powell. I just really enjoy his work. =)

Answer 5

Also, if you're having trouble getting the path of the resource (trickiest part) you can do a :

Assembly myAssembly = Assembly.GetExecutingAssembly();
string[] names = myAssembly.GetManifestResourceNames();
foreach (string name in names)
{
   Console.WriteLine( name );
} 

Which shows all paths for resources.
