Utf8JsonReader.ValueTextEquals Method

Definition

Namespace:

System.Text.Json

Assembly:

System.Text.Json.dll

Overloads

ValueTextEquals(ReadOnlySpan<Byte>)	Compares the UTF-8 encoded text in a read-only byte span to the unescaped JSON token value in the source and returns a value that indicates whether they match.
ValueTextEquals(ReadOnlySpan<Char>)	Compares the text in a read-only character span to the unescaped JSON token value in the source and returns a value that indicates whether they match.
ValueTextEquals(String)	Compares the string text to the unescaped JSON token value in the source and returns a value that indicates whether they match.

ValueTextEquals(ReadOnlySpan<Byte>)

Source:

Utf8JsonReader.cs

Compares the UTF-8 encoded text in a read-only byte span to the unescaped JSON token value in the source and returns a value that indicates whether they match.

public:
 bool ValueTextEquals(ReadOnlySpan<System::Byte> utf8Text);

public readonly bool ValueTextEquals (ReadOnlySpan<byte> utf8Text);

member this.ValueTextEquals : ReadOnlySpan<byte> -> bool

Public Function ValueTextEquals (utf8Text As ReadOnlySpan(Of Byte)) As Boolean

Parameters

utf8Text

ReadOnlySpan<Byte>

The UTF-8 encoded text to compare against.

Returns

Boolean

true if the JSON token value in the source matches the UTF-8 encoded lookup text; otherwise, false.

Exceptions

InvalidOperationException

The JSON token is not a JSON string (that is, it is not String or PropertyName).

Remarks

The lookup text must be valid UTF-8 text. Otherwise, this method could return true if the source has a string token containing invalid UTF-8 text that matches.

The comparison of the JSON token value in the source and the lookup text is done by first unescaping the JSON value in source, if required. The lookup text is matched as is, without any modifications to it.

ValueTextEquals(ReadOnlySpan<Char>)

Source:

Utf8JsonReader.cs

Compares the text in a read-only character span to the unescaped JSON token value in the source and returns a value that indicates whether they match.

public:
 bool ValueTextEquals(ReadOnlySpan<char> text);

public readonly bool ValueTextEquals (ReadOnlySpan<char> text);

member this.ValueTextEquals : ReadOnlySpan<char> -> bool

Public Function ValueTextEquals (text As ReadOnlySpan(Of Char)) As Boolean

Parameters

text

ReadOnlySpan<Char>

The text to compare against.

Returns

Boolean

true if the JSON token value in the source matches the lookup text; otherwise, false.

Exceptions

InvalidOperationException

The JSON token is not a JSON string (that is, it is not String or PropertyName).

Remarks

If the lookup text is invalid or incomplete UTF-16 text (that is, unpaired surrogates), the method returns false since you can't have invalid UTF-16 within the JSON payload.

ValueTextEquals(String)

Source:

Utf8JsonReader.cs

Compares the string text to the unescaped JSON token value in the source and returns a value that indicates whether they match.

public:
 bool ValueTextEquals(System::String ^ text);

public readonly bool ValueTextEquals (string? text);

member this.ValueTextEquals : string -> bool

Public Function ValueTextEquals (text As String) As Boolean

Parameters

text

String

The text to compare against.

Returns

Boolean

true if the JSON token value in the source matches the lookup text; otherwise, false.

Exceptions

InvalidOperationException

The JSON token is not a JSON string (that is, it is not String or PropertyName).

Remarks
