在C#中,使用linq如何将列表类型参数传递给方法
本文关键字:列表 类型 参数传递 方法 使用 linq | 更新日期: 2023-09-27 18:25:34
我有一种情况,我需要将数据存储在列表中,然后将相关字段传递给我的方法,我该如何做到这一点,请参阅下面的代码。
public static List<Supplier_Claim_Upload_Result> ExcludeFailedValidationRecords()
{
IList<CRMSupplierClaimsData> claimsData = GetClaimsUpdateRecordsFromStaging();
using (EmbraceEntities context = new EmbraceEntities())
{
var validatedList = context.Supplier_Claim_Upload(claimsData.LineNunber, claimsData.TotalClaim);// i get an error over here
return new List<Supplier_Claim_Upload_Result>(validatedList);
}
}
请尝试使用以下代码片段。您遇到错误,因为您试图访问集合中的属性来代替对象。
public static List<Supplier_Claim_Upload_Result> ExcludeFailedValidationRecords()
{
IList<CRMSupplierClaimsData> claimsData = GetClaimsUpdateRecordsFromStaging();
List<Supplier_Claim_Upload_Result> lst = new List<Supplier_Claim_Upload_Result>();
using (EmbraceEntities context = new EmbraceEntities())
{
foreach (var item in claimsData)
{
lst.AddRange(context.Supplier_Claim_Upload(item.LineNunber, item.TotalClaim));
}
}
return lst;
}
更新1:
public static List<Supplier_Claim_Upload_Result> ExcludeFailedValidationRecords()
{
IList<CRMSupplierClaimsData> claimsData = GetClaimsUpdateRecordsFromStaging();
List<Supplier_Claim_Upload_Result> lst = new List<Supplier_Claim_Upload_Result>();
using (EmbraceEntities context = new EmbraceEntities())
{
foreach (var item in claimsData)
{
var test = context.Supplier_Claim_Upload(item.LineNunber, item.TotalClaim);
lst.AddRange(test.ToList<Supplier_Claim_Upload_Result>());
}
}
return lst;
}
更新2:
public static List<Supplier_Claim_Upload_Result> ExcludeFailedValidationRecords()
{
IList<CRMSupplierClaimsData> claimsData = GetClaimsUpdateRecordsFromStaging();
List<Supplier_Claim_Upload_Result> lst = new List<Supplier_Claim_Upload_Result>();
using (EmbraceEntities context = new EmbraceEntities())
{
foreach (var item in claimsData)
{
var test = context.Supplier_Claim_Upload(item.LineNunber, item.TotalClaim);
foreach (var childitem in test)
{
lst.Add(childitem);
}
}
}
return lst;
}
如果有任何顾虑,请告诉我。
