尝试将当前实例的值格式化为提供的字符范围。

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

参数

destination: Span<Char>

写入此实例的值的格式为字符范围的范围。

charsWritten: Int32

此方法返回时，包含写入 destination的字符数。

format: ReadOnlySpan<Char>

一个范围，包含表示定义可接受的格式的标准或自定义格式字符串的 destination字符。

provider: IFormatProvider

一个可选对象，它提供区域性特定的格式设置信息 destination。

Boolean

true 如果格式设置成功，则为否则，为 false.

实现

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

注解

此接口的实现应生成与同一类型的实现 ToString(String, IFormatProvider) 相同的字符字符串。 TryFormat 仅当目标缓冲区中没有足够的空间时，才返回 false 。任何其他失败都应引发异常。
