c# - Interface reference -

I doubt, I have searched a lot about it and I have not found anything that can explain.

I can have the property referenced to an interface inside my class, and could use DI to fill these properties. For example:

  public interface iTest {void DoSomething (); } Public Sector Exam {ITest _test; Public Test (Itte_ Test) {this._test = test; }}   
 The problem is, if I have a generic interface, and my class does not use generic, when I make this property a compound error has increased  < Former>  Public Interface ITest & lt; T & gt; {Zero doSomething (T parameter); } Public Sector Exam {ITest & lt; T & gt; _testing; // Error (type can not be found) Public Test (Est  T & gt; _test) {this._test = test; }}   
 Is this possible?   
 
 
 Your  test  class also needs to be generic - otherwise this thing There is no way to know what type of  ITest & lt; T & gt;   _test  How do you know how to call  _test.DoSomething () ? The type parameter of  Test  does not have to be  T , of course:  
  test of public class & lt; TFoo & gt; {ITest & lt; TFoo & gt; _testing; Public examination (ITate & Lt; TFU & gt; _test) {this._test = test; }}   
 Then you can create it as:  
  ITest & lt; String & gt; X = ...; The & lt; String & gt; Test = new test & lt; String & gt; (X);   
 Type  Pause  by typing:  
  test & lt; Int & gt; Test = new test & lt; Int & gt; (X);   
 Because you have  test & lt; Int & gt;  a  ITest & lt; String & gt; .  
 Alternatively, your  test  class may only need to take a specific type of  ITest , and therefore can not be general:  
  public class test {ITest & lt; Guid & gt; _testing; Public exam (ITeSte & Lt; Guid & gt; _test) {this._test = test; }}   
 It all depends on what you are trying to achieve.  
 EDIT: As mentioned in the comments, if your  test  class  ITest & lt; T & gt; Does not use any aspect of , which you trust on  T , you want to create a non-normal base interface:  
  Public Interaction Item {void DoSomethingBland (); } Public Interaction Eyetest & lt; T & gt; : ITest {Zero dozoomings specific (tfu); }   
 Then you can only assign your class to  ITest & lt; T & gt;  instead of non-normal  ITest  can depend on the interface.
