Is there an equivalent to typedef in c#?

ie something like

typedef Dictionary<string, string> mydict;

I swear I have seen it but cannot find it

There is delegate, which is used for defining a type of method argument,

there is using BlaBla = Full.Name.Space.Yada.Yada;

however, the using statement is only valid in current file.

use inheritance:

public class DoubleNameValueCollection : Dictionary< string, NameValueCollection > { }

Then use as if it were a typedef:

NameValueCollection values = new NameValueCollection();
values.Add( "value1", "value2" );
DoubleNameValueCollection dblNameCol = new DoubleNameValueCollection();
dblNameCol.Add( "key1", values );

Or if you want to confuse others:

DoubleNameValueCollection dblNameCol = new DoubleNameValueCollection
    {
        { "key1", new NameValueCollection 
            {
                { "value1", "value2" }
    }}};

Sort of. 

using IntList = System.Collections.Generic.List<int>;

http://arbel.net/2004/07/07/the-hidden-c-typedef/

One issue is there is no way to #include the definition.

There is no equivalent of typedef in C#, however you could use 'using' for aliases.

using MyDict = Dictionary<String, String> which is like defining a symbol which would be replaced by the compiler.
