[英]Registering an open Generic Service erroneously asks me for type arguments
I have a Generic Repository which takes a Generic DbContext and a Generic Model,我有一个通用存储库,它采用通用 DbContext 和通用模型,
The Code I have is just a basic Generic Repository like so;我拥有的代码只是一个基本的通用存储库,就像这样;
public class DataRepo<T,M> : IDataRepo<T,M> where T:DbContext where M :class
{
private readonly T _Context;
private readonly M _Model;
public DataRepo(T Context, M model)
{
_Context = Context;
_Model = model;
}
public void Delete()
{
_Context.Remove(_Model);
}
public async Task<IEnumerable<T>> GetAll()
{
var results = await _Context.Set<T>().AsQueryable().AsNoTracking().ToListAsync();
return results;
}
public T GetSingleByID(int ID)
{
return _Context.Find<T>(ID);
}
public void InsertBulkItems(ICollection<M> dataModels)
{
_Context.AddRange(dataModels);
}
public void InsertSingleItem()
{
_Context.Add(_Model);
}
public void UpdateItem()
{
_Context.Update(_Model);
}
}
when I try to register this Service in Startup.cs, the compiler asks me for type arguments when according to this link I shouldn't be getting this error?当我尝试在 Startup.cs 中注册此服务时,编译器要求我输入类型参数,而根据此链接,我不应该收到此错误?
services.AddScoped(typeof(IDataRepo<>), typeof(DataRepo<>));
The Error I get is this;我得到的错误是这样的;
CS0305 Using the generic type 'IDataRepo' requires 2 type arguments CS0305 使用泛型类型“IDataRepo”需要 2 个类型参数
Could someone point me in the right direction with this please?有人能指出我正确的方向吗?
Because you have multiple generic arguments, you will need to include a comma in the generic arguments因为您有多个泛型参数,所以您需要在泛型参数中包含一个逗号
services.AddScoped(typeof(IDataRepo<,>), typeof(DataRepo<,>));
to properly represent how many generic arguments are needed for the types involved正确表示所涉及的类型需要多少个泛型参数
