错误 cs1729 不包含构造函数

Question

相同的代码在 1 个项目中有效，而在其他项目中无效。任何其他方式来写这个。 我得到的错误是错误 CS1729：“评估”不包含带有 12 个参数的构造函数。当我复制到 diff 项目中时，它编译并且运行良好。尝试清理临时 asp.net 文件，但没有帮助。

public class Assessment
{ 
   public Assessment(Guid assessmentId,string applicationId,string assessmentType,   Guid requestedBy,DateTime requestedDate,Guid assessmentOwner,string applicationToTest,
bool isCompleted,DateTime dateScheduled,DateTime datePerformed, GuidperformedBy,       string uri)
   {
        this.AssessmentId = assessmentId;      this.ApplicationId = applicationId;
        this.AssessmentType = assessmentType;  this.RequestedBy = requestedBy;
        this.RequestedDate = requestedDate;    this.AssessmentOwner = assessmentOwner;
        this.ApplicationToTest = applicationToTest; this.IsCompleted = isCompleted;
        this.DateScheduled = dateScheduled;    this.DatePerformed = datePerformed;
        this.PerformedBy = performedBy;        this.uri = uri;

   }

   public Assessment()
   {
        this.AssessmentId = Guid.NewGuid();    this.ApplicationId = string.Empty;
        this.AssessmentType = string.Empty;    this.RequestedBy = Guid.NewGuid();
        this.RequestedDate = DateTime.Now;     this.AssessmentOwner = Guid.NewGuid();
        this.ApplicationToTest = string.Empty; this.IsCompleted = false;
        this.DateScheduled = Convert.ToDateTime(DateScheduled);
        this.DatePerformed = Convert.ToDateTime(DatePerformed);
        this.PerformedBy = Guid.NewGuid();   this.uri = string.Empty;

   }
 public Guid AssessmentId  { get;     set;  }                
 public string ApplicationId   {get;  set;  }

Answer 1

要调查的事情：

1. 在其他命名空间中是否还有其他名为Assessment 的类定义？
2. 检查您的项目参考。确保您引用的程序集包含正确的 Assessment 定义。您可能在不知不觉中引用了该程序集的旧版本。
3. 使用 ILSpy 等反汇编程序检查包含 Assessment 的程序集。验证它包含正确的类定义。

Answer 2

发布的代码显示了Assessment 类的开始。该类没有关闭}。

然后有一个函数调用（通常是页面类的一部分）创建一个新的评估类。

所以我猜这是你加入的两个文件来解释你的问题。这意味着您没有在页面类中包含 using - 或者名称中有拼写错误，或者在您的项目中引用了不同的文件。

Assessment 类也可能没有编译，但有一个先前编译的版本正在链接。

类似的东西。无论如何，这不是您使用的确切代码，因此我们不可能找出问题所在。你可以在某处放完整代码（bitbucket？），然后我们就可以看到问题所在了。
