Good day

I have created a method with a dictionary. The data of the dictionary is coming from a stored procedure.

The data is as follows:

ReplacementStatusID      Description
1	                 Active	
2	                 Logged
3	                 Head Office
4	                 African Resonance	
5	                 Terminal Replace	
6	                 Inactive

//Method for the dictionary

C#

public void dctRplStatus()
       {
               Dictionary<string, int> objdic = new Dictionary<string, int>();
               objdic = clsIngadmin.SelectdicReplacementStatus();
               cmbRplStatus.DisplayMember = "Key";
               cmbRplStatus.ValueMember = "Value";
               cmbRplStatus.DataSource = new BindingSource(objdic, null);
               objdic = null;
           }
          }

How can I return a speceifc value that are inside of the dictionary. For example I want to return "Logged" that can display in a messagbox.

Thanx

The easiest way would be to use the inbuilt ContainsValue method[^].
E.g. Console.Writeline(objdic.ContainsValue("Logged"));

Another way could be to use LINQ on the dictionary.

Must I write anothor method and call the dictionary inside the method with the ContainsValue method?

No that is not required. You can do this within the same method.

Hi,
I presume you want to return Key rather than the Value in your dictionary, if so, you can use the following lambada expression to return "Logged" for example:

C#

object obj = objdic.Where(item => item.Value == 2).First().Key;

it return "Logged" which is one of the keys in your dictionary.
I hope it works!

Cheers,
