Formatting my string.

Question

Hello, how can I format a string like this:

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

I remember I used to be able to put a comma at the end and specify the actual data to assign to {0},{1}, etc.

Any help?

Answer 1

Use string.Format method such as in:

string X = string.Format("'{0}','{1}','{2}'", foo, bar, baz);

Answer 2

Use string.Format as in

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

Answer 3

String.Format("'{0}', '{1}'", arg0, arg1);

Answer 4

The String.Format method accepts a format string followed by one to many variables that are to be formatted. The format string consists of placeholders, which are essentially locations to place the value of the variables you pass into the function.

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

Answer 5

Your question is a bit vague, but do 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?

Answer 6

are you looking for:

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

would result in

"String with data Foo, Bar I wish to format"

Answer 7

An alternative is to use Join, if you have the values in a string array:

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

Answer 8

use string.format, and put individual format specifiers inside the braces, after the number and a 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 the single quotes to delineate literals, anything not inside braces will be output literally
