自定义数组比较或查找在另一个数组中不存在的值

我有两个自定义类，

  1. BeneficiaryResponse和
  2. BeneficiaryDetail

都有key Id和AliasName字段。

我想在Linq查询的帮助下，从第一类中找到那些缺失的值，即受益人响应，这在受益人详细信息中不存在。如。受益人响应有30个参数，受益人有20个参数，然后我想要从受益人响应中缺少的10个参数。

public class BeneficiaryDetail
{
     public BeneficiaryDetail[] beneInternal
     {
        get;
        set;
     }
     public int? Id
     {
        get;
        set;
     }
     public string AliasName
     {
        get;
        set;
     }
}
public class BeneficiaryResponse
{
    public int Id
    {
        get;
        set;
    }
    public string AliasName
    {
        get;
        set;
    }
}

现在受益人响应有以下内容，

[{" Id ": 763886年,"AliasName":"abc - 3594"},
{" Id ": 763759,"AliasName":"abc - 6789"},
{" Id ": 763661,"AliasName":"abc - 9111"},
{" Id ": 763668,"AliasName":"abc - 9111"},
{" Id ": 764467,"AliasName":"abc - 3594"}]

和BeneficiaryDetail有

[{" Id ": 763886年,"AliasName":"abc - 3594"},
{" Id ": 763759,"AliasName":"abc - 6789"},
{" Id ": 764467,"AliasName":"abc - 3594"}]

如何从BeneficiaryResponse中获得2个缺失的其余部分

自定义数组比较或查找在另一个数组中不存在的值

添加Newtonsoft。Josn dll 

    public void Main(string[] args)
    {
        string strBR = "[{ 'Id':763886,'AliasName':'ABC-3594'},{ 'Id':763759,'AliasName':'ABC-6789'},{ 'Id':763661,'AliasName':'ABC-9111'},{ 'Id':763668,'AliasName':'ABC-9111'},{ 'Id':764467,'AliasName':'ABC-3594'}]";
        string strBD = " [{'Id':763886,'AliasName':'ABC-3594'},{'Id':763759,'AliasName':'ABC-6789'},{'Id':764467,'AliasName':'ABC-3594'}]";
        var resultBR = JsonConvert.DeserializeObject<List<BeneficiaryResponse>>(strBR);
        var resultBD = JsonConvert.DeserializeObject<List<BeneficiaryDetail>>(strBD);
        var missingData = resultBR.Where(x => !resultBD.Select(n => n.Id).Contains(x.Id)).ToList();
        foreach (var item in missingData)
        {
            Console.WriteLine(item.Id);
        }
    }
    public class BeneficiaryResponse
    {
        public int Id { get; set; }
        public string AliasName { get; set; }
    }
    public class BeneficiaryDetail
    {
        public int Id { get; set; }
        public string AliasName { get; set; }
    }

输出:763661 763668

您可以使用以下linq代码进行输出。它将根据ID参数给出输出。这可能对你有帮助。

var result= (from c in BeneficiaryResponse 
             where !(from o in BeneficiaryDetail select o.ID).Contains(c.ID)  
             select c);

或

var result= from BResponse in BeneficiaryResponse 
            where !(BeneficiaryDetail.Any
                   (BDetail => BDetail.ID == Response.ID 
                    && BDetail.AliasName == BResponse.AliasName))
            select BResponse;
