How to convert enum to type

Question

I have a enum like this.

public enum eTypeVar
{
    Int,
    Char,
    Float
};

and I want to convert it to type , to do something like this:

eTypeVar type=eTypeVar .Int;
string str= eTypeVar.ToString .ToLower();
(str as type) a=1;

How would I do it?

Answer 1

You can use Enum.Parse such as:

YourEnumType realValue = Enum.Parse(typeof(YourEnumType), "int");

Answer 2

I think what you need is:

Dictionary<eTypeVar, Type> _Types = new Dictionary<eTypeVar, Type> {
    { eTypeVar.Int, typeof(Int32) },
    { eTypeVar.Char, typeof(Char) },
    { eTypeVar.Float, typeof(Single) }
};

public Boolean Check(eTypeVar type, Object value)
{
    return value.GetType() == _Types[type];
}

You cannot convert a variable into a type for another variable declaration. You should rethink your design. Anyway it doesn't make sence what you are doing. If you know that you want to use a int, why not declare it:

String name = "int";
int value = 1;

If you want to have dynamic code for some reasons you could use Reflection and a generic method.

public void DoSomething<T>(T value)
{
    ....
}

Then you can construct the method at runtime using reflection and invoke it. But at this time i think you need more basics of C# to work with this features.

Answer 3

you can try this... for example you have enum like this

  public enum Emloyee
 {
   None = 0,
  Manager = 1,
  Admin = 2,
  Operator = 3
}

then convert enum to this

Emloyee role = Emloyee.Manager;
int roleInterger = (int)role;

end for enum to string..

Emloyee role = Emloyee.Manager;
string roleString = role.ToString();
