How to provide custom string placeholder for string format

Question

I have a string

string str =\"Enter {0} patient name\";

I am using string.format to format it.

String.Format(str, \"Hello\         


        

Answer 1

object[] myInts = new int[] {8,9}; 

However you can get away with:

object[] myInts = new string[] { "8", "9" }; 
string bar = string.Format("{0} {1}", myInts);
