        int age;
        float sal;

        public nav(string s,int i,float sl)
        {
            name=s;
            age=i;
            sal=sl;

        }
        public void showdata()
        {
        Console.WriteLine("Name:"+name);
        Console.WriteLine("Age:"+age);
        Console.WriteLine("Sal:"+sal);
        }


    }
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            nav nv=new nav("David Billa";,26,9000);
            nv.showdata();
        }
    }
}

what i meant to ask here is now i cannot use show data functionality to display the values of the NV object in a text box cause they are combo values i.e. string,int...etc. how to make them in display!

What i wanted to achieve here is the values that can be displayed when nv.showdata() is used...i want those values to be displayed in a text box,label,msg box etc!

i know that the following code will display the output of the program in a console(dos). what is my question here is what should me done to get the output in textbox.msg box etc. how ever i have two ideas!

1) to redirect the console output into a textbox
2) rewrite the method to display the output in a textbox,msg box etc

which would be better! i know the first one though! but i guess its not a correct way!

Rewrite it to do what? It is not clear what you are trying to achieve.

The best way is probably to have ShowData return a value: a string or an array of strings perhaps:

C#

public string showdata()
    {
    StringBuilder sb = new StringBuilder();
    sb.AppendFormat("Name: {0}\n", name);
    sb.AppendFormat("Age:  {0}\n", age);
    sb.AppendFormat("Sal:  {0}\n", sal);
    return sb.ToString();
    }

However, what I would do is change the name to ToString, and override the default version:

C#

public override string ToString()
    {
    StringBuilder sb = new StringBuilder();
    sb.AppendFormat("Name: {0}\n", name);
    sb.AppendFormat("Age:  {0}\n", age);
    sb.AppendFormat("Sal:  {0}\n", sal);
    return sb.ToString();
    }

Then you can print it:

C#

Console.Write(nc);

or whatever you want to do with it!

Solution 2

By the time I posted my answer, OriginalGriff has already posted his answer. However, I think this answer may also be helpful.
Return a string of values from the ShowData method. It is better to rename it as GetData to make the intent of method obvious.

C#

public string GetData()
{
    return string.Format("Name:{0}{3}Age:{1}{3}Salary:{2}", 
            name, age, sal, System.Environment.NewLine);
}
//To display it in a TextBox
TextBox1.MultiLine=true;
TextBox1.Text = nv.GetData();
//To display it in a label
Label1.Text = nv.GetData();
