Overloads

TryGetProperty(String, JsonElement)

Looks for a property named propertyName in the current object, returning a value that indicates whether or not such a property exists. When the property exists, its value is assigned to the value argument.

TryGetProperty(ReadOnlySpan<Byte>, JsonElement)

Looks for a property named utf8PropertyName in the current object, returning a value that indicates whether or not such a property exists. When the property exists, the method assigns its value to the value argument.

TryGetProperty(ReadOnlySpan<Char>, JsonElement)

Looks for a property named propertyName in the current object, returning a value that indicates whether or not such a property exists. When the property exists, the method assigns its value to the value argument.

Looks for a property named propertyName in the current object, returning a value that indicates whether or not such a property exists. When the property exists, its value is assigned to the value argument.

public:
 bool TryGetProperty(System::String ^ propertyName, [Runtime::InteropServices::Out] System::Text::Json::JsonElement % value);
public bool TryGetProperty (string propertyName, out System.Text.Json.JsonElement value);
member this.TryGetProperty : string * JsonElement -> bool
Public Function TryGetProperty (propertyName As String, ByRef value As JsonElement) As Boolean

Parameters

propertyName
String

The name of the property to find.

value
JsonElement

When this method returns, contains the value of the specified property.

Returns

true if the property was found; otherwise, false.

Exceptions

propertyName is null.

The parent JsonDocument has been disposed.

Remarks

Property name matching is performed as an ordinal, case-sensitive comparison.

If a property is defined multiple times for the same object, the method matches the last such definition.
