System.Drawing.Image.FromFile() does not work (?)

Question

1.33/5 (2 votes)

See more:

I am using visual studio 9.0. The .net framework version is 2.0. I need to use the System.Drawing.Image.FromFile() method. The compiler reports that this function does not exist. In documention, it is written that this function is in file "System.Drawing.dll". I have included that file but still the error has not gone. Whole code looks like below:

C#

using System;
using System.Collections.Generic;
using System.Text;
using System.Drawing;
using System.Resources;
namespace Res
{
    class Program
    {
        static void Main(string[] args)
        {
            Image img = System.Drawing.Image.FromFile("aa.gif");
        }
    }
}

The compiler error I am getting is "The System.Drawing.Image does not contain a definition for 'FromFile()'."
I need to use this function. Can anyone help me to ressolve my issue. Thanks in advance.

How did you include System.Drawing.dll - did you right click on your project and use add reference to add a reference to the System.Drawing assembly?

System.Drawing.Image.FromFile is declared as

C#

public static Image FromFile(
    string filename
)

so, as far as I can tell, your code should compile ...

You are not creating an instance of the Image class in your code, that happens somewhere inside FromFile.

This is good answer - my 5. As to v.2.0 -- I confirm the method is supported, see my answer.

Thanks for your answer. Perhaps that the dll I was referencing was not compelete. I downloaded System.Drawing.dll from internet and referenced it. The method worked. Thanks a lot for your support as I thought that this method would be removed from newer .net version. Thanks once again.

As you are not using .net 4.0 framework along VS9.0,just check if the overload you are trying to provide is supported in .net 2.0 .Even if the name of method is existing & overload not supported,it may throw does not contain defenition.I executed your line of code in my vs9.0 & it runs perfectly fine.

Solution 1

It's supposed to be:

C#

Bitmap img = (Bitmap)Image.FromFile("aa.gif", true);

The Image class is an abstract class and cannot be instantiated.

I think it would also be wise to use the fully qualified path to retrieve the file instead of just the file name.

Solution 4

I thought this method does not compile in Framework 2.0, but I immediately found a confirmation it does exist:

http://msdn.microsoft.com/en-us/library/system.drawing.image.fromfile(v=vs.80).aspx[^]

This method even existed in Framework v.1.1:

http://msdn.microsoft.com/en-us/library/system.drawing.image_members(v=VS.71).aspx[^]

So, please check things up.
