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

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

:)))

Answer 2

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 3

This does throw an OutOfMemoryException :

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

Answer 4

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

Answer 5

var x = new long[Int32.MaxValue];

应该这样做。

Answer 6

你可以用这个：

new int[(ulong)-1];
