public:
bool TryFormat(Span<char> destination, [Runtime::InteropServices::Out] int % charsWritten, ReadOnlySpan<char> format, IFormatProvider ^ provider);
public bool TryFormat (Span<char> destination, out int charsWritten, ReadOnlySpan<char> format, IFormatProvider? provider);
abstract member TryFormat : Span<char> * int * ReadOnlySpan<char> * IFormatProvider -> bool
Public Function TryFormat (destination As Span(Of Char), ByRef charsWritten As Integer, format As ReadOnlySpan(Of Char), provider As IFormatProvider) As Boolean
The span in which to write this instance's value formatted as a span of characters.
- charsWritten
- Int32
When this method returns, contains the number of characters that were written in destination
.

.
- provider
- IFormatProvider
An optional object that supplies culture-specific formatting information for destination
.
true
if the formatting was successful; otherwise, false

- An implementation of this interface should produce the same string of characters as an implementation of ToString(String, IFormatProvider) on the same type.
- TryFormat should return false only if there is not enough space in the destination buffer. Any other failures should throw an exception.
