Question

Is there a cool way to take something like this:

Customer Name - City, State - ID
Bob Whiley - Howesville, TN - 322
Marley Winchester - Old Towne, CA - 5653

and format it to something like this:

Customer Name     - City,       State - ID
Bob Whiley        - Howesville, TN    - 322
Marley Winchester - Old Towne,  CA    - 5653

Using string format commands?

I am not too hung up on what to do if one is very long. For example this would be ok by me:

Customer Name     - City,       State - ID
Bob Whiley        - Howesville, TN    - 322
Marley Winchester - Old Towne,  CA    - 5653
Super Town person - Long Town Name, WA- 45648 

To provide some context. I have a drop down box that shows info very similar to this. Right now my code to create the item in the drop down looks like this:

public partial class CustomerDataContract
{
    public string DropDownDisplay
    {
        get
        {
             return  Name + " - " + City + ",  " + State + " - " + ID;
        }
    }
}

I am looking for a way to format this better. Any ideas?

This is what I ended up with:

HttpContext.Current.Server.HtmlDecode(
    String.Format("{0,-27} - {1,-15}, {2, 2} - {3,5}", 
    Name, City, State, ID)
    .Replace(" ", " "));

The HtmlDecode changes the   to a space that can withstand the space removing formatting of the dropdown list.

You can specify the number of columns occupied by the text as well as alignment using Console.WriteLine or using String.Format:

// Prints "--123       --"
Console.WriteLine("--{0,-10}--", 123);
// Prints "--       123--"
Console.WriteLine("--{0,10}--", 123);

The number specifies the number of columns you want to use and the sign specifies alignment (- for left alignment, + for right alignment). So, if you know the number of columns available, you could write for example something like this:

public string DropDownDisplay { 
  get { 
    return String.Format("{0,-10} - {1,-10}, {2, 10} - {3,5}"),
      Name, City, State, ID);
  } 
} 

If you’d like to calculate the number of columns based on the entire list (e.g. the longest name), then you’ll need to get that number in advance and pass it as a parameter to your DropDownDisplay – there is no way to do this automatically.
