Can we return more than one value through function/method in C#

[amitjaura]

The coding on which I am working is::

 private String infoPatient()
        {
            String initial;
            String transplantDate;

            openConnection();
            SqlDataAdapter adpGender = new SqlDataAdapter("select gender from tblRegistration where pID='"+patientID+"'", con);
            DataTable dtGender = new DataTable();
            adpGender.Fill(dtGender);
            initial = dtGender.Rows[0][0].ToString()=="Male" ? "Mr" : "Mrs";
            

            SqlDataAdapter adpTransplantDate = new SqlDataAdapter("select crossdate from txnpatientEvaluationFirst where patientID='"+patientID+"' and dateOfupdate=(select max(dateOfUpdate) from txnpatientEvaluationFirst where patientID='"+patientID+"')", con);
            DataTable dtTransplantDate = new DataTable();
            adpTransplantDate.Fill(dtTransplantDate);
            transplantDate = (Convert.ToDateTime(dtTransplantDate.Rows[0][0].ToString())).Date.ToLongDateString();
           }

Now I want to return values transplantDate and iniatial

There are several approaches which you could take;

You could change the return type to a collection or array of strings

You could make the return type a collcetion of objects and then casting is not required.

You could keep the return type as a single string, then concatinate the two values with a seperator like a ";" and then split them again in another function.

Or you could define a new class which stores the two values in the correct type and then pass an instance of that class.

Good luck

You could also do this, for example:

 private String infoPatient(out String transplantDate)
 {
     // rest of your code here
     return initial;
 }

where here I am returning one of the values, transplantDate, as an "out" parameter to the function, and returning the other one, initial, as a normal function return.

The Best way could be using "Out" Keyword... The code may be like:

private String infoPatient(out String initial,out String transplantDate )
{............
.............
}

There is no need of return statement then...But Make sure using "out" kyword while Calling this Functio..Like :

infoPatient(out initial,out transplantDate );

All the Best.

infoPatient(out initial,out transplantDate );

How will we get values returned by the
infoPatient(out initial,out transplantDate )
This function will return two values (initial,transp lantDate).Shoul d we get the values in collection?

Also you used the return type of function as string but we have two values to return....what if the two values are of different type?

I think that you missed everyone's point.

There are several ways to do it.
The "out" method doesn't actually "return" the values...but it gets a reference to the parameters that are being passed to it. The objects you used to call that method will be updated. They don't have to be returned.

Or, (the way I would do it) is that you can write a simple class with the properties that you need. Then use objects of that class type.

Or like was suggested you can use a return type of object[] and cast back after you are done.

There are plenty of possibilities.

Thank you everybody

I have used a class returning the values and I am using object of that class
and it is doing good:
the coding is:::::

public class info
    {
        String initial,transplantDate;
       public info(String initial, String transplantDate)
       {
           this.initial = initial;
           this.transplantDate = transplantDate;
       }

        public string initial1
     {
          get
          {
               return initial; 
          }
     }
     // Gets our Second Result (string)
     public string transplant1
     {
         get
         {
             return transplantDate;
         }
     }

Thank you evrybody once again
