C# 用插值器展平

我尝试使用将多个对象映射到视图模型对象。但它并没有像我预期的那样起作用

代码：

class Call
{
    public string Number { get; set; }
    public string CustomerNumber { get; set; }
}

class Operation
{
    public int ID { get; set; }
    public string CallNumber { get; set; }
    public string TimeFrom { get; set; }
}

class Customer
{
    public string Number { get; set; }
    public string Name { get; set; }
}

class CallViewModel
{
    public string Number { get; set; }
    public string CustomerName { get; set; }
    public string OperationTimeFrom { get; set; }
}

class Test
{
    static void Main(string[] args)
    {
        var call = new Call { Number = "001337", CustomerNumber = "000001" };
        var op = new Operation { ID = 1, CallNumber = "001337", TimeFrom = "08:00" };
        var customer = new Customer { Number = "000001", Name = "John Doe" };

        var viewModel = new CallViewModel();
        viewModel.InjectFrom(call, op, customer);

        Console.WriteLine("Number:\t\t\t" + viewModel.Number);
        Console.WriteLine("CustomerName:\t\t" + viewModel.CustomerName);
        Console.WriteLine("OperationTimeFrom:\t" + viewModel.OperationTimeFrom);
        Console.ReadLine();
    }
}

Number:            001337
CustomerName:      John Doe
OperationTimeFrom: 08:00

Number:            00001
CustomerName:      
OperationTimeFrom: 

预期输出：

class Call
{
    public string Number { get; set; }
    public string CustomerNumber { get; set; }
}

class Operation
{
    public int ID { get; set; }
    public string CallNumber { get; set; }
    public string TimeFrom { get; set; }
}

class Customer
{
    public string Number { get; set; }
    public string Name { get; set; }
}

class CallViewModel
{
    public string Number { get; set; }
    public string CustomerName { get; set; }
    public string OperationTimeFrom { get; set; }
}

class Test
{
    static void Main(string[] args)
    {
        var call = new Call { Number = "001337", CustomerNumber = "000001" };
        var op = new Operation { ID = 1, CallNumber = "001337", TimeFrom = "08:00" };
        var customer = new Customer { Number = "000001", Name = "John Doe" };

        var viewModel = new CallViewModel();
        viewModel.InjectFrom(call, op, customer);

        Console.WriteLine("Number:\t\t\t" + viewModel.Number);
        Console.WriteLine("CustomerName:\t\t" + viewModel.CustomerName);
        Console.WriteLine("OperationTimeFrom:\t" + viewModel.OperationTimeFrom);
        Console.ReadLine();
    }
}

Number:            001337
CustomerName:      John Doe
OperationTimeFrom: 08:00

Number:            00001
CustomerName:      
OperationTimeFrom: 

有效输出：

class Call
{
    public string Number { get; set; }
    public string CustomerNumber { get; set; }
}

class Operation
{
    public int ID { get; set; }
    public string CallNumber { get; set; }
    public string TimeFrom { get; set; }
}

class Customer
{
    public string Number { get; set; }
    public string Name { get; set; }
}

class CallViewModel
{
    public string Number { get; set; }
    public string CustomerName { get; set; }
    public string OperationTimeFrom { get; set; }
}

class Test
{
    static void Main(string[] args)
    {
        var call = new Call { Number = "001337", CustomerNumber = "000001" };
        var op = new Operation { ID = 1, CallNumber = "001337", TimeFrom = "08:00" };
        var customer = new Customer { Number = "000001", Name = "John Doe" };

        var viewModel = new CallViewModel();
        viewModel.InjectFrom(call, op, customer);

        Console.WriteLine("Number:\t\t\t" + viewModel.Number);
        Console.WriteLine("CustomerName:\t\t" + viewModel.CustomerName);
        Console.WriteLine("OperationTimeFrom:\t" + viewModel.OperationTimeFrom);
        Console.ReadLine();
    }
}

Number:            001337
CustomerName:      John Doe
OperationTimeFrom: 08:00

Number:            00001
CustomerName:      
OperationTimeFrom: 

注意

CallViewModel

中表示为

Number

的

Call.Number

被

Customer.Number

覆盖。

CustomerName

和

OperationTimeFrom

都无法获取其指定源

Customer.Name

和

Operation.TimeFrom

的值

在这种情况下我必须做什么？ValueInjector支持这种情况吗？

我猜您考虑过用另一种方式进行扁平化， 它的工作方式是你从

obj.Prop.Prop1.Prop2 to obj.PropProp1Prop2

这是您修改的代码：

using System;
using Omu.ValueInjecter;

namespace ConsoleApplication1
{
    class Program
    {
        private static void Main(string[] args)
        {
            var call = new Call { Number = "001337", CustomerNumber = "000001" };
            var op = new Operation { ID = 1, CallNumber = "001337", TimeFrom = "08:00" };
            var customer = new Customer { Number = "000001", Name = "John Doe" };

            var model = new
                            {
                                Call = call,
                                Customer = customer,
                                Operation = op
                            };

            var viewModel = new CallViewModel();
            viewModel.InjectFrom<FlatLoopValueInjection>(model);

            Console.WriteLine("Number:\t\t\t" + viewModel.CallNumber);
            Console.WriteLine("CustomerName:\t\t" + viewModel.CustomerName);
            Console.WriteLine("OperationTimeFrom:\t" + viewModel.OperationTimeFrom);
            Console.ReadLine();
        }

        class Call
        {
            public string Number { get; set; }
            public string CustomerNumber { get; set; }
        }

        class Operation
        {
            public int ID { get; set; }
            public string CallNumber { get; set; }
            public string TimeFrom { get; set; }
        }

        class Customer
        {
            public string Number { get; set; }
            public string Name { get; set; }
        }

        class CallViewModel
        {
            public string CallNumber { get; set; }
            public string CustomerName { get; set; }
            public string OperationTimeFrom { get; set; }
        }
    }
}

使用系统；
使用Omu.valueinjector；
命名空间控制台应用程序1
{
班级计划
{
私有静态void Main（字符串[]args）
{
var call=新呼叫{Number=“001337”，CustomerNumber=“000001”}；
var op=新操作{ID=1，CallNumber=“001337”，TimeFrom=“08:00”}；
var customer=新客户{Number=“000001”，Name=“John Doe”}；
var模型=新
{
呼叫，
客户=客户，
操作=op
};
var viewModel=new CallViewModel（）；
viewModel.InjectFrom（model）；
Console.WriteLine（“编号：\t\t\t”+viewModel.CallNumber）；
Console.WriteLine（“CustomerName:\t\t”+viewModel.CustomerName）；
Console.WriteLine（“OperationTimeFrom:\t”+viewModel.OperationTimeFrom）；
Console.ReadLine（）；
}
集体电话
{
公共字符串编号{get；set；}
公共字符串CustomerNumber{get；set；}
}

{
公共int ID{get；set；}
公共字符串CallNumber{get；set；}
公共字符串TimeFrom{get；set；}
}

公共字符串名称{get；set；}
}
类CallViewModel
{
公共字符串CallNumber{get；set；}
公共字符串CustomerName{get；set；}
公共字符串操作timefrom{get；set；}
}
}
}

我在发帖之前就试过了。我使用了

viewModel.InjectFrom（call、op、customer）

但是以与上面相同的输出结束OK我现在知道

FlatLoopValueInjection

查找要匹配的属性名称。是否存在与类型名称匹配的注入？如果没有，可以创建一个吗？@Sandro你可以，只需查看FlatLoopValueInjection的源代码
