public delegate void MeasurementCallback(Instrument ^ instrument, T measurement, ReadOnlySpan<KeyValuePair<System::String ^, System::Object ^>> tags, System::Object ^ state);
generic <typename T>
 where T : value classpublic delegate void MeasurementCallback(Instrument ^ instrument, T measurement, ReadOnlySpan<KeyValuePair<System::String ^, System::Object ^>> tags, System::Object ^ state);
public delegate void MeasurementCallback<T>(Instrument instrument, T measurement, ReadOnlySpan<KeyValuePair<string,object?>> tags, object? state);
public delegate void MeasurementCallback<T>(Instrument instrument, T measurement, ReadOnlySpan<KeyValuePair<string,object?>> tags, object? state) where T : struct;
type MeasurementCallback<'T> = delegate of Instrument * 'T * ReadOnlySpan<KeyValuePair<string, obj>> * obj -> unit
type MeasurementCallback<'T (requires 'T : struct)> = delegate of Instrument * 'T * ReadOnlySpan<KeyValuePair<string, obj>> * obj -> unit
Public Delegate Sub MeasurementCallback(Of T)(instrument As Instrument, measurement As T, tags As ReadOnlySpan(Of KeyValuePair(Of String, Object)), state As Object)

类型参数
