'Creating Variables By string text

I am looking to create variables by string value. Is there smarter way to do it?

if (str == "DateTime")
{
        DateTime d = new DateTime();
}

else if( str == "TimeSpan")
{
        TimeSpan s = new TimeSpan();
}

I want to write something like that:

object o = new someString() ` when someString is "DateTime" or "TimeSpan"`

Solution 1:[1]

You can do something like this which does the same thing but more concisely:

object o = str switch
{
    "DateTime" => new DateTime(),
    "TimeSpan" => new TimeSpan(),
    _ => throw new NotImplementedException()
};

It would be helpful to know what you want to do with the variable afterwards, however, because there might be better ways if you provide context.

Solution 2:[2]

May be you can use the dynamic variables, and check the type of it in runtime. eg:

dynamic str ;
        str = DateTime.Now.TimeOfDay;
        if(str.GetType()==typeof(System.TimeSpan))
        {
            Console.Write("hello");
        }
