Question

I have two equally sized arrays, arrayKeys and arrayValues filled with data, respectively for Keys and Values, and an empty Dictionary<K, V>(myDictionary). I would like to assign as Keys and Values of the Dictionary the elements in each array. I know that this can be done by using the following code:

for(i=0:i<arrayKeys.Lenght;i++)
{
   myDictionary.Add(arrayKeys[i], arrayValue[i]);
}

but I would like to know whether is there any way to perform the assignment as follows:

myDictionary.Keys = arrayKeys;
myDictionary.Values = arrayValues;

maybe by using lambdas with the ToDictionary method. Thanks in advance

Answer 1

You can write

myDictionary = keys.Zip(values, (k, v) => new { k, v })
                   .ToDictionary(o => o.k, o => o.v);
