String.PadRight Method (Int32, Char)


Returns a new string that left-aligns the characters in this string by padding them on the right with a specified Unicode character, for a specified total length.

Namespace:   System
Assembly:  mscorlib (in mscorlib.dll)

public string PadRight(
	int totalWidth,
	char paddingChar


Type: System.Int32

The number of characters in the resulting string, equal to the number of original characters plus any additional padding characters.

Type: System.Char

A Unicode padding character.

Return Value

Type: System.String

A new string that is equivalent to this instance, but left-aligned and padded on the right with as many paddingChar characters as needed to create a length of totalWidth. However, if totalWidth is less than the length of this instance, the method returns a reference to the existing instance. If totalWidthis equal to the length of this instance, the method returns a new string that is identical to this instance.

Exception Condition

totalWidth is less than zero.

The PadRight(Int32, Char) method pads the end of the returned string. This means that, when used with right-to-left languages, it pads the left portion of the string.


If the PadRight method pads the current instance with whitespace characters, this method does not modify the value of the current instance. Instead, it returns a new string that is padded with trailing paddingChar characters so that its total length is totalWidth characters.

The following example demonstrates the PadRight method.

string str = "forty-two";
char pad = '.';

Console.WriteLine(str.PadRight(15, pad));    // Displays "forty-two......".
Console.WriteLine(str.PadRight(2,  pad));    // Displays "forty-two".
