Return Value

A new String that is equivalent to this instance, but right-aligned and padded on the left with as many paddingChar characters as needed to create a length of totalWidth. Or, if totalWidth is less than the length of this instance, a new String that is identical to this instance.

Exception typeCondition


totalWidth is less than zero.

The PadLeft(Int32,Char) 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.

The following code example demonstrates the PadLeft method.

String^ str = "forty-two";
Console::WriteLine( str->PadLeft( 15, L'.' ) ); // Displays "......forty-two".
Console::WriteLine( str->PadLeft( 2, L'.' ) );  // Displays "forty-two".
