试图将通用 id 传递给类构造函数

Question

我的班级低于LibrarySourceTableInput 并且具有这样的结构

public class LibrarySourceTableInput<T> where T: ISourceOfData
{      
    public LibrarySourceTableInput(List<T> libraries, string mappedLibrarySource)
    {
        this.LibrarySourceRowInputs = libraries?.Select(l => new LibrarySourceRowInput()
            {
                LibrarySourceId = l.Id,
                SourceOfDataId = l.SourceOfData.Id
            }).ToList() ?? new(),
         this.MappedLibrarySource = mappedLibrarySource;
    }
    public List<LibrarySourceRowInput> LibrarySourceRowInputs { get; set; }
    public string MappedLibrarySource { get; set; }
}

然后接口ISourceOfData结构如下所示

public interface ISourceOfData : IIdentity
{
    public new Guid Id { get; set; }
    public CodeStandardGuideline SourceOfData { get; set; }
}

我正在像这样在其他地方调用上面的类构造函数

var mechanicalData = spaceTypeObject.TargetObject.MechanicalData;                           
 var librarySourceTableInputs = new List<LibrarySourceTableInput<ISourceOfData>>
 {
     new LibrarySourceTableInput<ISourceOfData>(mechanicalData?.Environments, mappedLibrarySource), // I am getting conversion error here 
     new LibrarySourceTableInput<ISourceOfData>(mechanicalData?.AirflowsA621 , mappedLibrarySource)
     .......
     .......
 }

mechanicaldata.environments 的结构是这样的

public class MechanicalData
{
    public List<LibraryEnvironment> Environments { get; set; }
    public List<LibraryA621> AirflowsA621 { get; set; }
    .......
}

然后最后一个 libraryEnvironment 类是这样的

 public class LibraryEnvironment : ISourceOfData
 {
    public virtual CodeStandardGuideline SourceOfData { get; set; }
    .....
    ......
    public Guid Id {get; set;}     
 }

我在这一行遇到以下错误new LibrarySourceTableInput<ISourceOfData>(mechanicalData?.Environments, mappedLibrarySource)

错误是Cannot convert from Generic.List<LibraryEnvironment> to Generic.List<IsourceOfData>

任何人都可以让我知道或知道如何将该通用列表发送到该类构造函数，非常感谢。

不要指定接口 ISourceOfData（您的类已经知道该类型将具有该接口），而是指定实际类：

var librarySourceTableInputs = new List<LibrarySourceTableInput<LibraryEnvironment>>
{
    new LibrarySourceTableInput<LibraryEnvironment>(mechanicalData?.Environments, mappedLibrarySource),
     .......
     .......
}
