Re initializing objects

I have an application which needs re initialization every time I process. something like : 

private void method(int someValue, int someValue2)
{
 obj.val1 = someNewValue;
 obj1.Val2 = someNewValue2;
}

This method will be called repeatedly. So I doubt is it okey to re initialize the object every time? something like; 

private void method(int someValue, int someValue2)
{
 obj = new object();
 obj.Val1 = someNewValue;
 obj1.Val2 = someNewValue2;


}

I know assigning null to an object is nothing fruitful to do with. or should I implement IDisposable ? The problem is I need fresh values every time.Assigning will be ok in this scenario? I dont know what will happen to the already allocated object if i reinitialize as shown in second method.

"Reference objects" need to be disposed (by calling Dispose()) only if they use unmanaged memory. All such objects (in the .NET class libraries) implement IDisposable. Managed objects, on the other hand, are automatically collected (deleted) by the Garbage Collector behind-the-scene. In fact there is no direct way of deleting a managed object. You should not worry about such objects. As soon as they go out of scope, GC will eventually release their memory.

Simply assigning a new value to a managed variable releases the reference of the previous value and therefore makes it available for deletion by the GC.

is this Object a custom class? If so i would write a "Reset()" method to do all the resetting you'd need.

for example you would call

private void method(int someValue, int someValue2)
{
 obj.Reset();
 obj.Val1 = someValue;
 obj1.Val2 = someValue2;
}

and in the Reset function you would do whatever you need to consider the object "re-initialised"

i.e

public void Reset()
{
    this.Val1 = 0;
    this.Val2 = 0;
    this.Name = "";
    this.Date = DateTime.MinDate;
    //You get the Idea, reset whatever needed to whatever you need.
}

using this function you can also then, in the constructor simply call "Reset();" so you know the values are the same when another method calls "Reset" on this object along with a new object being made.
