如何在Asp Net内核中将存储过程的XML输出转换为C#对象

存储过程的实际输出

将包含这些信息的最后一列

我想在我的dot net Core Web应用程序中调用此存储过程。

根据您的描述，如果您已经使用EF Core创建了数据库，并且可以使用

\u dbContext..FromSqlRaw

方法接收存储过程数据。我建议您可以尝试为EF创建一个定制，以满足您的需求

当您使用EF core从sqldatbase获取数据时，valueconvert可以将字符串转换为对象，当您希望将数据插入数据库时，valueconvert会将对象转换为字符串

更多详细信息，请参考以下代码：

首先，您应该创建StateWiseCompany类

SET ANSI_NULLS ON; GO SET QUOTED_IDENTIFIER ON; GO ALTER PROC
[dbo].[getStateWiseCompanyDetails] AS
BEGIN
With Data
     AS (SELECT Companies.RegionId,
                Companies.Code,
                Companies.CompanyName,
                Users.FirstName,
                Companies.OfficePhone
         FROM Companies
              INNER JOIN Users ON Companies.DirectorId = Users.Id)
     SELECT States.Id AS RegionId,
            States.StateName,
            States.IsRegion AS Status,
            Users.FirstName + ' ' + Users.LastName AS RegionDirector,
            Users.PhoneNumber,
     (
         SELECT *
         FROM Data
         WHERE data.RegionId = States.Id FOR XML PATH('CompanyList'), ROOT('StateWiseCompany'), TYPE
     ) AS CompanyList
     FROM States
          INNER JOIN Users ON States.RegionDirector = Users.Id;
END;

第四，我建议您修改dbcontext以覆盖OnModelCreating方法，如下所示：

public class Organization
{
    [Key]
    public int OrgID { get; set; }
    public StateWiseCompany OrgName { get; set; }
}

结果:

数据库：

查询结果：

欢迎来到Stackoverflow。请以文本而不是图片的形式共享您的代码。您能告诉我您现在使用了哪个sql库吗？EF核心？否则呢？你知道如何从数据库中获取数据吗？或者您只是想知道如何将xml转换为对象？谢谢，它已经成功了。我们可以只用两个类来完成吗？

public class ObjectToDbStringEquivalentConvertor<T> : ValueConverter<T, string>
{
    public ObjectToDbStringEquivalentConvertor(ConverterMappingHints mappingHints = null) : base(convertToProviderExpression, convertFromProviderExpression, mappingHints)
    { }

    private static Expression<Func<T, string>> convertToProviderExpression = x => ToDbString(x);
    private static Expression<Func<string, T>> convertFromProviderExpression = x => ToObject<T>(x);

    public static string ToDbString<T>(T obj)
    {

        using (var stringwriter = new System.IO.StringWriter())
        {
            var serializer = new XmlSerializer(typeof(T));
            serializer.Serialize(stringwriter, obj);
            return stringwriter.ToString();
        }

     }

    public static T ToObject<T>(string stringValue)
    {
        if (stringValue != string.Empty)
        {
            using (var stringReader = new System.IO.StringReader(stringValue))
            {
                var serializer = new XmlSerializer(typeof(T));
                var re = serializer.Deserialize(stringReader);
                return (T)re;
            }
        }
        else
        {
            throw new Exception();
        }
  
    }



}

public class Organization
{
    [Key]
    public int OrgID { get; set; }
    public StateWiseCompany OrgName { get; set; }
}

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);

        modelBuilder.Entity<Organization>(
            entity => {
                entity.HasKey(e => e.OrgID);
                entity.Property(e => e.OrgName).HasConversion(new ObjectToDbStringEquivalentConvertor<StateWiseCompany>());
                }
           
            ) ;

    }

        var re = _dbContext.Organizations.FromSqlRaw("EXEC [dbo].[getStateWiseCompanyDetails]").ToList();
