What's the easiest way to get an OutOfMemoryException in C#?

Question

Just curious as to how I can get this error the easiest way.

Once I was trying to create a file navigator and I was creating Image thumbnails; that turned out awful.

Answer 1

Create a very, very large string. Probably:

string s = new string('a', int.MaxValue);

will be enough.

If not, you can concat it to build even bigger string.

string ss = string.Concat(s, s);

Answer 2

void Foo()
{
   throw new OutOfMemoryException();
}

:)))

Answer 3

This does throw an OutOfMemoryException:

string s = " ";
while (true) s += s;

Answer 4

Well, it is not the easiest way to get this error, but when dealing with images, it could cause this error, even if there is much memory free:

Confusingly, an OutOfMemoryException is thrown from the System.Drawing.Image.FromFile method when an image format or the pixel format of an image is not supported by the .net framework.

See: http://msdn.microsoft.com/en-gb/library/stf701f5.aspx

I don't know why there is no ImageFormatNotSupportedYetException ;(

Answer 5

for(var s=" ";;s+=s);
