Question

I have a Dictionary with some key-value pairs stored in it. My problem is that in my dictionary, I have a blank space at the start of the key name, so for accessing the value, I have to use:

Pair[" Key"];

Is there any method where I can remove the starting whitespace, so I can access the value like:

Pair["Key"]

Answer 1

Trimming your string is enough. Besides that you can also write a custom key comparer for your dictionary instead of trimming your string everytime you add or get something to/from your dictionary.

Dictionary<string, int> dict = new Dictionary<string, int>(new Comparer());
dict.Add("aa ", 10);
int i = dict[" aa"];

public class Comparer : IEqualityComparer<string>
{
    public bool Equals(string x, string y)
    {
        return x.Trim().Equals(y.Trim());
    }

    public int GetHashCode(string obj)
    {
        return obj.Trim().GetHashCode();
    }
 }
