Return Value
Type: System.StringA new string that is equivalent to this instance, but right-aligned and padded on the left with as many spaces 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 totalWidth is equal to the length of this instance, the method returns a new string that is identical to this instance.
| Exception | Condition |
|---|---|
| ArgumentOutOfRangeException | totalWidth is less than zero. |
A Unicode space is defined as hexadecimal 0x0020.
The PadLeft(Int32) method pads the beginning of the returned string. This means that, when used with right-to-left languages, it pads the right portion of the string.

If the PadLeftmethod 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 leading white space so that its total length is totalWidth characters. |
