How Can I Exclude Properties from JSON Serialization in C#?

Exclude JSON serialization properties in C#

When serializing a DTO, you may need to exclude specific attributes from the generated JSON. If the property is declared public, you can use several mechanisms to achieve this exclusion.

Json.Net

The

[JsonIgnore] attribute allows you to explicitly ignore a field or attribute during serialization and deserialization.

<code class="language-csharp">[JsonIgnore]
public DateTime LastModified { get; set; }</code>

DataContract and DataMember

Alternatively, you can use the DataContract and DataMember attributes to selectively determine which properties are included or excluded from serialization.

<code class="language-csharp">[DataContract]
public class Computer
{
    [DataMember]
    public string Name { get; set; }

    // 不包含在序列化中
    public string Manufacture { get; set; }
}</code>
