Overloads

Create(IFormatProvider, DefaultInterpolatedStringHandler)	Creates a new string by using the specified provider to control the formatting of the specified interpolated string.
Create(IFormatProvider, Span<Char>, DefaultInterpolatedStringHandler)	Creates a new string by using the specified provider to control the formatting of the specified interpolated string.

Create(IFormatProvider, DefaultInterpolatedStringHandler)

Source:

String.cs

Creates a new string by using the specified provider to control the formatting of the specified interpolated string.

public:
 static System::String ^ Create(IFormatProvider ^ provider, System::Runtime::CompilerServices::DefaultInterpolatedStringHandler % handler);

public static string Create (IFormatProvider? provider, ref System.Runtime.CompilerServices.DefaultInterpolatedStringHandler handler);

static member Create : IFormatProvider * DefaultInterpolatedStringHandler -> string

Public Shared Function Create (provider As IFormatProvider, ByRef handler As DefaultInterpolatedStringHandler) As String

Parameters

provider

IFormatProvider

An object that supplies culture-specific formatting information.

handler

DefaultInterpolatedStringHandler

The interpolated string, passed by reference.

Returns

String

The string that results for formatting the interpolated string using the specified format provider.

Create(IFormatProvider, Span<Char>, DefaultInterpolatedStringHandler)

Source:

String.cs

Creates a new string by using the specified provider to control the formatting of the specified interpolated string.

public:
 static System::String ^ Create(IFormatProvider ^ provider, Span<char> initialBuffer, System::Runtime::CompilerServices::DefaultInterpolatedStringHandler % handler);

public static string Create (IFormatProvider? provider, Span<char> initialBuffer, ref System.Runtime.CompilerServices.DefaultInterpolatedStringHandler handler);

static member Create : IFormatProvider * Span<char> * DefaultInterpolatedStringHandler -> string

Public Shared Function Create (provider As IFormatProvider, initialBuffer As Span(Of Char), ByRef handler As DefaultInterpolatedStringHandler) As String

Parameters

provider

IFormatProvider

An object that supplies culture-specific formatting information.

initialBuffer

Span<Char>

The initial buffer that may be used as temporary space as part of the formatting operation. The contents of this buffer may be overwritten.

handler

DefaultInterpolatedStringHandler

The interpolated string, passed by reference.

Returns

String

The string that results for formatting the interpolated string using the specified format provider.

Create<TState>(Int32, TState, SpanAction<Char,TState>)

Source:

String.cs

Creates a new string with a specific length and initializes it after creation by using the specified callback.

public:
generic <typename TState>
 static System::String ^ Create(int length, TState state, System::Buffers::SpanAction<char, TState> ^ action);

public static string Create<TState> (int length, TState state, System.Buffers.SpanAction<char,TState> action);

static member Create : int * 'State * System.Buffers.SpanAction<char, 'State> -> string

Public Shared Function Create(Of TState) (length As Integer, state As TState, action As SpanAction(Of Char, TState)) As String

Type Parameters

TState

The type of the element to pass to action.

Parameters

length

Int32

The length of the string to create.

state

TState

The element to pass to action.

action

SpanAction<Char,TState>

A callback to initialize the string.

Returns

String

The created string.

Remarks

The initial content of the destination span passed to action is undefined. Therefore, it is the delegate's responsibility to ensure that every element of the span is assigned. Otherwise, the resulting string could contain random characters.

To support interop scenarios, the underlying buffer is guaranteed to be at least 1 greater than represented by the span parameter of the action callback. This additional index represents the null-terminator and, if written, that is the only value supported. Writing any value other than the null-terminator corrupts the string and is considered undefined behavior.
