Comparison Operator in C#

I have a vague requirement. I need to compare two values. The values may be a number or a string.

I want to perform these operations >, <, ==,<>, >=,<=

In my method I will pass, the parameter1, parameter 2 and the operators of above.

How can compare the two values based on the operator as effectively in .NET 2.0.

My method should be as simplified开发者_如何学Go for both String and integer input values.

Sample Input Value:

param1  |  param2  |  operator

Provided both parameters are always of the same type you could use a generic method where both parameters implement IComparable<T> (introduced in .NET 2.0)

public int CompareItems<T>(T item1, T item2) where T: IComparable<T>
{
    return item1.CompareTo(item2);
}

(You can interpret the result of CompareTo() depending on the operator your pass in your implementation)

If you have to/want to build generic version you need to pass comparison as function/lambda - it is not possible to use operators in generic way. Somithing like:

class OpComparer<T>
{
  Func<T,T,bool> operation;
  public OpComparer(Func<T,T,bool> op)
  {
    operation = op;
  }

  int PerformOp(T item1, T item2) 
  {
    return operation(item1, item2);
  }
}

...
var comparerLess = new OpCompared<String>((a,b)=> a < b );
var result = comparerLess.PerformOp("aaa", "bbb");
