C# | Linq | SubSonic - Class object

Question

I have this class/object below:

public class Person
{
  public  string FirstName;
  public  string MI;
  public  string LastName;
}

Person p=new Person();
      p.FirstName = "Jeff";
      p.MI = "A";
      p.LastName = "Price";

Is there any built in in linq or c# or in subsonic that will create an output of this?:

string myString = "FirstName=\"Jeff\" p.MI=\"A\" p.LastName=\"Price\"";

Answer 1

It seems you need a ToString overload in Person. Also, don't expose public fields like that. Use properties.

    public class Person
    {
        public string FirstName { get; set; }
        public string MI { get; set; }
        public string LastName { get; set; }

        public override string ToString()
        {
            return "FirstName=\"" + FirstName + "\" p.MI=\"" + MI + "\" p.LastName=\"" + LastName + "\"";
        }
    }

(edit)

Here's your request (but it requires properties):

    public static class ObjectPrettyPrint
    {
        public static string ToString(object obj)
        {
            Type type = obj.GetType();
            PropertyInfo[] props = type.GetProperties();
            StringBuilder sb = new StringBuilder();
            foreach (var prop in props)
            {
                sb.Append(prop.Name);
                sb.Append("=\"");
                sb.Append(prop.GetValue(obj, null));
                sb.Append("\" ");
            }

            return sb.ToString();
        }
    }

Usage:

        Console.WriteLine(ObjectPrettyPrint.ToString(new Person { FirstName, = "A", MI = "B", LastName = "C"  }));

Well, as for LINQ and C#, not by default.

However, in the Person class you can override the ToString() event to do it for you.

    public override string ToString()
    {
        return string.Format("p.Firstname={0} p.MI={1} p.LastName={2}", FirstName, MI, LastName);
    }

And then you would just call it as follows:

string myString = p.ToString();

Which will give you the output you are looking for.
