Can not convert type int to T-CodePudding

I run into a compiler error that I am not sure how to resolve it.

Basically, I have a few enum classes described below.

I created abstract classes myTool and myTools deriving from myTool. The compiler for some reason does not like the way I structured the constructor for MyTools and threw error

CS0030: Can not convert type int to type T.

Please advice me how to resolve this.

public enum TOOLS
{
  HAMMER =1,
  DRILL = 2,
  SCREWDRIVER =3,
  VACUUM=4
}

public enum EQUIPMENTS
{
  MOWER=1,
  TRIMMER=2,
  SNOWBLOWER=3
}

public abstract class MyTool
{
  protected T _myStuff
  int quantity
  double price
  public MyTool(T t)
  {
  _myStuff =t;
  }
  ... properties...
}

public abstract class MyTools<T>:myTool<T>
where T:System.Enum
{
  protected MyTool<T>[] _myTools;
  public MyTool<T> this[int i]=> this._myTools[i];
  public MyTools(int count, T t):base(t)
  {
    _myTools = new MyTools<T>[count];
    for (int i=0; i<count;i  )
    {
      _myTools[i]=(T)(i 1);
    }
  }
}

CodePudding user response：

You can convert an int into a generic type constrained as System.Enum like this:

T enumValue = (T)Enum.ToObject(typeof(T), intValue);

or simply

T enumValue = (T)(object)intValue;

CodePudding user response：

You can use generic type converter

public static class TConverter
{
 public static T ChangeType<T>(object value)
 {
     return (T)ChangeType(typeof(T), value);
 }

 public static object ChangeType(Type t, object value)
 {
    TypeConverter tc = TypeDescriptor.GetConverter(t);
    return tc.ConvertFrom(value);
 }

 public static void RegisterTypeConverter<T, TC>() where TC : TypeConverter
 {

    TypeDescriptor.AddAttributes(typeof(T), new TypeConverterAttribute(typeof(TC)));
 }
}

and usage:

 TConverter.ChangeType<T>(intValue);
