嘗試將目前實例的值格式化為提供的字元範圍。

public:
 virtual 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 = default, IFormatProvider? provider = default);
public bool TryFormat(Span<char> destination, out int charsWritten, ReadOnlySpan<char> format, IFormatProvider? provider);
abstract member TryFormat : Span<char> * int * ReadOnlySpan<char> * IFormatProvider -> bool
override this.TryFormat : Span<char> * int * ReadOnlySpan<char> * IFormatProvider -> bool
Public Function TryFormat (destination As Span(Of Char), ByRef charsWritten As Integer, Optional format As ReadOnlySpan(Of Char) = Nothing, Optional provider As IFormatProvider = Nothing) As Boolean
Public Function TryFormat (destination As Span(Of Char), ByRef charsWritten As Integer, format As ReadOnlySpan(Of Char), provider As IFormatProvider) As Boolean

參數

destination
Span<Char>

寫入這個實例值的範圍，格式為字元範圍。

charsWritten
Int32

當這個方法傳回時，會包含以 destination撰寫的字元數。

format
ReadOnlySpan<Char>

範圍，包含代表標準或自定義格式字串的字元，定義 destination可接受的格式。

provider
IFormatProvider

選擇性物件，提供 destination的特定文化特性格式資訊。

傳回

Boolean

如果格式設定成功，true;否則，false。

實作

TryFormat(Span<Char>, Int32, ReadOnlySpan<Char>, IFormatProvider)

備註

這個介面的實作應該會產生與相同類型上 ToString(String, IFormatProvider) 實作相同的字元字串。 只有當目的地緩衝區中沒有足夠的空間時，TryFormat 才會傳回 false。 任何其他失敗都應該擲回例外狀況。
