Question

Can I use string.Format like this?

1 ) Replace Number to String

string sample = "Hello, {name}";

//I want to put a name string into {name}, is it possible?

**2 ) Is it possible add strings one by one to string template

string sample = "My name is {0}, I am living in {1} ...";

// put {0} value
// and put {1} value separately

ex)
sample[0] = "MIKE";
sample[1] = "Los Anageles";

Answer 1

1:

string sample1 = "Hello, {name}";
Console.WriteLine(sample1.Replace("{name}", "John Smith"));

2:

string sample2 = "My name is {0}, I am living in {1} ..."; 
var parms = new ArrayList();
parms.Add("John");
parms.Add("LA");
Console.WriteLine(string.Format(sample2, parms.ToArray()));
