示例

Response<BasicDigitalTwin> getBasicDtResponse = await client.GetDigitalTwinAsync<BasicDigitalTwin>(basicDtId);
BasicDigitalTwin basicDt = getBasicDtResponse.Value;

// Must cast Component1 as a JsonElement and get its raw text in order to deserialize it as a dictionary
string component1RawText = ((JsonElement)basicDt.Contents["Component1"]).GetRawText();
var component1 = JsonSerializer.Deserialize<BasicDigitalTwinComponent>(component1RawText);

Console.WriteLine($"Retrieved and deserialized digital twin {basicDt.Id}:\n\t" +
    $"ETag: {basicDt.ETag}\n\t" +
    $"ModelId: {basicDt.Metadata.ModelId}\n\t" +
    $"LastUpdatedOn: {basicDt.LastUpdatedOn}\n\t" +
    $"Prop1: {basicDt.Contents["Prop1"]}, last updated on {basicDt.Metadata.PropertyMetadata["Prop1"].LastUpdatedOn}\n\t" +
    $"Prop2: {basicDt.Contents["Prop2"]}, last updated on {basicDt.Metadata.PropertyMetadata["Prop2"].LastUpdatedOn} and sourced at {basicDt.Metadata.PropertyMetadata["Prop2"].SourceTime}\n\t" +
    $"Component1.LastUpdatedOn: {component1.LastUpdatedOn}\n\t" +
    $"Component1.Prop1: {component1.Contents["ComponentProp1"]}, last updated on: {component1.Metadata["ComponentProp1"].LastUpdatedOn}\n\t" +
    $"Component1.Prop2: {component1.Contents["ComponentProp2"]}, last updated on: {component1.Metadata["ComponentProp2"].LastUpdatedOn} and sourced at: {component1.Metadata["ComponentProp2"].SourceTime}");

如果 属性是组件，请使用 BasicDigitalTwinComponent 类反序列化有效负载。
