Mapster -如何忽略null属性的映射

using Mapster;

// 定义源对象和目标对象
public class SourceObject
{
    public string Name { get; set; }
    public int? Age { get; set; }
    public string Address { get; set; }
}

public class DestinationObject
{
    public string Name { get; set; }
    public int? Age { get; set; }
    public string Address { get; set; }
}

// 创建映射配置
var config = new TypeAdapterConfig();
config.ForType<SourceObject, DestinationObject>()
    .IgnoreNullValues(true); // 忽略源对象中的null属性

// 执行映射
var source = new SourceObject { Name = "John", Age = null, Address = "123 Street" };
var destination = source.Adapt<DestinationObject>(config);

// 输出结果
Console.WriteLine(destination.Name);    // 输出: John
Console.WriteLine(destination.Age);     // 输出: null
Console.WriteLine(destination.Address); // 输出: 123 Street
