Question

我无法将SourceModel数据映射到DestinationModel数据。 DestinationModel具有复杂的对象类型。虽然名称匹配，但是我看不到任何数据正确绑定。我是ValueInjector的新手，根据我的理解，这是我尝试过的方法。

public class SourceModel
{
    [Column("ctr_shname")]
    public string CtrShname { get; set; }

    [Column("reg_name")]
    public string RegName { get; set; }

    [Column("Male")]
    public Int64 Male { get; set; }

    [Column("Female")]
    public Int64 Female { get; set; }

    [Column("Single")]
    public Int64 Single { get; set; }

    [Column("Married")]
    public Int64 Married { get; set; }

    [Column("Divorced")]
    public Int64 Divorced { get; set; }

    [Column("Separated")]
    public Int64 Separated { get; set; }

    [Column("Widowed")]
    public Int64 Widowed { get; set; }
}

public class DestinationModel
{
    public string CtrShname { get; set; }
    public string RegName { get; set; }
    public Gender Genders { get; set; }
    public MaritalStatus MaritalStatuses { get; set; }
}

public class Gender
{
    public Int64 Male { get; set; }
    public Int64 Female { get; set; }
}

public class MaritalStatus
{
    public Int64 Single { get; set; }
    public Int64 Married { get; set; }
    public Int64 Divorced { get; set; }
    public Int64 Separated { get; set; }
    public Int64 Widowed { get; set; }
}

这是我要映射的代码。

// get data from DB (row count 123)
IEnumerable<SourceModel> data = GetDataFromDB();
List<DestinationModel> finalAnswer = new List<DestinationModel>();

// Try 1: all properties are null for all 123 records
finalAnswer.InjectFrom(data);

// Try 2: Zero count. Nothing gets binds
var mapper1 = new MapperInstance();
finalAnswer = mapper1.Map<List<DestinationModel>>(data);

请帮助我如何正确映射？

我认为ValueInjector仅允许注入单个对象，但是您可以这样做。

   IEnumerable<SourceModel> data = GetDataFromDB();
IList<DestinationModel> finalAnswer = categoryList
    .Select(x => new DestinationModel().InjectFrom(x)).Cast<DestinationModel>()
    .ToList();

或者做一个foreach并注入每个对象：

foreach (var a in data)
{
    finalAnswer.InjectFrom(a);
}
