  Hi guys,

  My array list is like this: 

  ArrayList arrayList = new ArrayList() { 1, "abc", 33.5M };
  
  How can I get concatenated output of each object? Thanks.

  Hi.

  You can do by:

      StringBuilder a = new StringBuilder();
      foreach (object obj in arrayList) a.Append(obj);
      string str = a.ToString();

  Thanks.

  Hi kamalhussain,

  According to your requirement,you could also use String.Join to concatenate array list.

  For example:

  ArrayList arrayList = new ArrayList() { 1, "abc", 33.5M };
  
  var list = String.Join("", arrayList.ToArray());

  How it works:

  

  Best Regards.
