Formatting my string

How can I format the string like this:

string X = "'{0}','{1}','{2}','{3}','{4}','{5}','{6}','{7}','{8}','{9}','{10}','{11}','{12}','{13}'",????

I remember that earlier I could put a comma at the end and give the actual data to assign to {0}, {1}, etc.

Any help?

An alternative is to use Join if you have values ​​in an array of strings:

string x = "'" + String.Join("','", valueArray) + "'";


(Just wanted to be different from users 89724362 showing you how to use String.Format ...;)

The method String.Format

accepts a format string followed by one to many variables to be formatted. The format string is made up of placeholders, which are essentially places to place the values ​​of the variables that you pass to the function.

Console.WriteLine(String.Format("{0}, {1}, {2}", var1, var2, var3));

Your question is a little vague, but you mean:

// declare and set variables val1 and val2 up here somewhere
string X = string.Format("'{0}','{1}'", val1, val2);

Or are you asking for something else?

use string.format and put the individual format specifiers inside curly braces, after the number and colon, as in

   string s = string.Format(
        " {0:d MMM yyyy} --- {1:000} --- {2:#,##0.0} -- {3:f}",
        DateTime.Now, 1, 12345.678, 3e-6);

and as you can see from the example, you don't need single quotes to delimit literals, anything not inside curly braces will be output literally

Use string.Format

as in

var output = string.Format("'{0}', '{1}'", x, y);

You are looking for:

String.Format("String with data {0}, {1} I wish to format", "Foo", "Bar");

will lead to

"Data string Foo, Bar I want to format"
