Compare two dictionaries and add missing keys.Values not important at this time

dictionary1 looks like this

[DATA_WZD],[WERKZEUG],NUMM=1,GRUP=1,AKR=0,MODE=1,MAGA=1,LAGE=0,DURC=348.2,........NOTCH=130,MANCH=0,RED3=0,NAME="Querschnittblatt 350-3,5mm ",BEME="Bemerkung "
[WERKZEUG],NUMM=2,GRUP=1,MAKR=0,MODE=0,MAGA=0,LAGE=0,DURC=449.6........NOTCH=150,MANCH=0,RED3=0,NAME="Querschnittblatt 450/4,0mm ",BEME="Bemerkung "
[WERKZEUG] and so on.

dictionary2 looks similar, but has extra keys and values

[DATA_WZD]
[WERKZEUG],NUMM=1,GRUP=1,MAKR=0,MODE=0,MAGA=0,LAGE=0,DURC=385.8,.......NOTCH=130,MANCH=0,RED3=0,CYCLE=0,CMIN=0,CMAX=0,ACTIVE=1,NAME="Querschnittblatt 35",BEME="Bemerkung"
[WERKZEUG],NUMM=2,GRUP=1,MAKR=0,MODE=0,MAGA=0,LAGE=0,DURC=429.6........NOTCH=150,MANCH=0,RED3=0,CYCLE=0,CMIN=0,CMAX=0,ACTIVE=1,NAME="Querschnittblatt 45",BEME="Bemerkung"
[WERKZEUG].....

I want the keys and the values from dictionary2 which are missing in dictionary1 to be inserted at the same position in dictionary2. should than look like this

[DATA_WZD]
[WERKZEUG],NUMM=1,GRUP=1,AKR=0,MODE=1,MAGA=1,LAGE=0,DURC=348.2,........NOTCH=130,MANCH=0,RED3=0,CYCLE=0,CMIN=0,CMAX=0,ACTIVE=1,NAME="Querschnittblatt 350-3,5mm ",BEME="Bemerkung "
[WERKZEUG],NUMM=2,GRUP=1,MAKR=0,MODE=0,MAGA=0,LAGE=0,DURC=449.6........NOTCH=150,MANCH=0,RED3=0,CYCLE=0,CMIN=0,CMAX=0,ACTIVE=1,NAME="Querschnittblatt 450/4,0mm ",BEME="Bemerkung "
[WERKZEUG]......

What's a good way of doing this?

You could try using Linq:

dict1.Keys.Except(dict2.Keys)
          .ToList()
          .ForEach(k => dict2.Add(k, dict1[k]));

or if you want empty strings instead of dict1 values:

dict1.Keys.Except(dict2.Keys)
          .ToList()
          .ForEach(k => dict2.Add(k, string.Empty));

Here is a simple algorithm to merge two dictionaries in pseudo-code:

Given 

Dictionary dict1,dict2

Do this:

Dictionary dictRes = new Dictionary;


for each(key in dict1)
  dictRes.Add(dict1(key));

for each(key in dict2)
  if (not dictRes contains element)
    dictRes.Add(dict2(key));
