String.Format with null values C#

Anonymous User 7572 12-Dec-2013

I want to format an address. Here is my code:

address = String.Format("{0}, {1}, {2}, {3}, {4}, {5},
{6}",
                       
postalAddress.Line1,
postalAddress.Line2,
                       
postalAddress.Line3,
                       
postalAddress.Line4,
                       
postalAddress.Suburb,
                       
postalAddress.StateCode,
                       
postalAddress.Pcode);
Unfortunately this produces 116 Knox St, , , , Watson, ACT, 2602 when Line2, Line3, Line4 are null. How can I handle the nulls to get a results like 116 Knox St, Watson, ACT, 2602?

Hi Chintoo,

You can try this :

StringBuilder sb = new StringBuilder();

List<string> addressParts = new List<string> { postalAddress.Line1, postalAddress.Line2, postalAddress.Line3, postalAddress.Line4, postalAddress.Suburb, postalAddress.StateCode, postalAddress.Pcode };

addressParts.ForEach(x => sb.Append(String.IsNullOrEmpty(x) ? "" : ", " + x));

string address = sb.ToString().Trim(',');

Hope this will solve your problem.
