Formats strings that represent matrices of scalar types. Also applicable to jagged arrays of scalar types. VerboseFormatInfo delegates calls to this class when formatting two-dimensional arrays or jagged arrays of simple types. This class is internal and cannot be used directly.
Inheritance: VerboseFormatInfoBase
