none
about dispose? RRS feed

  • Question

  • I use Mat of OpencvSharp.

    for example, My code :

    Mat Computer(Mat m,double ex,double add,double mul){

         using(Mat p = m.Power(ex)) {

               using(Mat mu = p.Mul(mul){

                   Mat ad = mu.Add(add);

                   return ad;

               }

          }

    }

    I wish Code like this follow:

     

    Mat Computer(Mat m,double ex,double add,double mul){

        return m.Power(ex).Mul(mul).Add(add);

    }

    but this code raises one question:
    1、 raise memory out because of some temp variant can't dispose immediately and.

    How can I do?

  • You should ask this question here since this is a non Microsoft library.

  • my question is a opencvlib's question, but this question is commonly  in C# language.

    i will design  a class and it likes Mat's chain calling :

    for examle:

       object1.methd1().method2()....

    every calling constructor one temp variant.

    i have any way to control the memory dispose except "using",but it likes

    using(var temp1= objec1.method1())

         using(var temp2=temp1.mehtod2(){

                          ....................

         } 

    }

    The code looks very long and ugly.

    temp variants can auto release if i use C++ lanuage.

    how design in C# language ?  can't ?
