Question

I have a method I am not happy with, can you please show me how to do this better.

public Foo WithBar(IDictionary<string, object> parameters) {
    var strStrDict = new Dictionary<string, string>(parameters.Count);
    foreach(var pair in parameters)
    {
        strStrDict.Add(pair.Key, pair.Value != null ? pair.Value.ToString() : (string)null);
    }      
    // Call overload which takes IDictionary<string, string>  
    return this.WithBar(strStrDict);
}

This code works but I’m sure there is a nice linq’y way of doing this I am missing.

Answer 1

parameters.ToDictionary(k=>k.Key, v=>v.Value!=null?v.Value.ToString():(string)null);
