TextWriter.FormatProvider Property


Gets an object that controls formatting.

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

public virtual IFormatProvider FormatProvider { get; }

Property Value

Type: System.IFormatProvider

An IFormatProvider object for a specific culture, or the formatting of the current culture if no other culture is specified.

The value of the FormatProvider property specifies the culture-specific formatting that is used when you call the Write and WriteLine methods. If you do not want to provide a format provider, you create an instance by using the TextWriter() constructor, which sets the FormatProvider property to null. When the FormatProvider property contains null, the culture of the current thread is used for formatting.
