The format parameter can be any valid standard numeric format specifier except for D, R, and X, as well as any combination of custom numeric format specifiers. If format is null or an empty string, the return value of this instance is formatted with the general numeric format specifier (G).

The .NET Framework provides extensive formatting support, which is described in greater detail in the following formatting topics:

The return value is formatted with the NumberFormatInfo for the current culture.

The following example displays a Decimal value using each of the supported standard numeric format specifiers, together with two custom numeric format strings. In converting the numeric values to strings, the example uses the formatting conventions of the en-US culture.


decimal value = 16325.62m;
string specifier;

// Use standard numeric format specifiers.
specifier = "G";
outputBlock.Text += String.Format("{0}: {1}", specifier, value.ToString(specifier)) + "\n";
// Displays:    G: 16325.62
specifier = "C";
outputBlock.Text += String.Format("{0}: {1}", specifier, value.ToString(specifier)) + "\n";
// Displays:    C: $16,325.62
specifier = "E04";
outputBlock.Text += String.Format("{0}: {1}", specifier, value.ToString(specifier)) + "\n";
// Displays:    E04: 1.6326E+004
specifier = "F";
outputBlock.Text += String.Format("{0}: {1}", specifier, value.ToString(specifier)) + "\n";
// Displays:    F: 16325.62
specifier = "N";
outputBlock.Text += String.Format("{0}: {1}", specifier, value.ToString(specifier)) + "\n";
// Displays:    N: 16,325.62
specifier = "P";
outputBlock.Text += String.Format("{0}: {1}", specifier, (value / 10000).ToString(specifier)) + "\n";
// Displays:    P: 163.26 %

// Use custom numeric format specifiers.
specifier = "0,0.000";
outputBlock.Text += String.Format("{0}: {1}", specifier, value.ToString(specifier)) + "\n";
// Displays:    0,0.000: 16,325.620
specifier = "#,#.00#;(#,#.00#)";
outputBlock.Text += String.Format("{0}: {1}", specifier, (value * -1).ToString(specifier)) + "\n";
// Displays:    #,#.00#;(#,#.00#): (16,325.62)
