Question

I have the following Dictionary content :

[0] {75, SimpleObject}
[1] {56, SimpleObject}
[2] {65, SimpleObject}
[3] {12, SimpleObject}
...

I want to get first key, means 75, without foreach.

Maybe the key word should reffers to [0] not 75.

Because based on that key, I want to use that SimpleObject, I wrote:

SimpleObject s = dictionary[0] as SimpleObject;

but the VS2010 throws an exception:

The given key was not present in the dictionary.

I know that [0] means key number 0 from dictionary, means if I could have

[0] {72,  SimpleObject} //here
[1] {56, SimpleObject}
[2] {65, SimpleObject}
[3] {12, SimpleObject}
...

then I should get the correspondent SimpleObject.

Sorry, is first time using Dictionary and I want to learn more.

Question: How to get the number 75 and his SimpleObject ?

Thank you.

PS: I know that in StackOverflow already exists similar topic but no of them help me to get that key.

using System.Linq;

...

dictionary.First().Key // Returns 75
dictionary.First().Value // returns the related SimpleObject
