Parse(object)

This is a convenience method for Parse(string) that can be used as a Converter.

Declaration
public static object Parse(object str)
Parameters
Type Name Description
object str
Returns
Type Description
object

Parse(string)

This static method can be used to read in a Margin from a string that was produced by Stringify(Margin).

Declaration
public static Margin Parse(string str)
Parameters
Type Name Description
string str
Returns
Type Description
Margin
Remarks

Margin.Parse("1 2 3 4") produces the Margin new Margin(1, 2, 3, 4). This function will throw an error on invalid strings.

Stringify(Margin)

This static method can be used to write out a Margin as a string that can be read by Parse(string).

Declaration
public static string Stringify(Margin val)
Parameters
Type Name Description
Margin val
Returns
Type Description
string
Remarks

Margin.Stringify(new Margin(1, 2, 3, 4)) produces the string "1 2 3 4".

Stringify(object)

This is a convenience method for Stringify(Margin) that can be used as a BackConverter.

Declaration
public static object Stringify(object marg)
Parameters
Type Name Description
object marg
Returns
Type Description
object

ToString()

Returns a string representation of the margin.

Declaration
public override string ToString()

Type Description
string

A string representation of the current margin.
