Hi there I just noticed a odd behaviour from my class. My class is a class that knows how to connect to a device using the ethernet, send some information to the device, retreive a response from the device and then close the connection to the device. Until now I thought things were going smoothly, but today I wanted to improve the speed of the connect,send,receive, disconnect process.

In a button click I create my object

ALS.Device.SBox oSBox = new ALS.Device.SBox();

One of the properties of my class is:

private static System.Int32 _CumulativeDataRead = 0;
public System.Int32 CumulativeDataRead
{
  get{ return SBox._CumulativeDataRead;}
}

Now the first time I click the button every thing is fine (CumulativeDataRead = 0), but the next time I click the button the value returned by CumulativeDataRead is equal to the number of bytes I received with the last transmission (CumulativeDataRead=281). The object oSBox is scoped to the button click method so you think it would be disposed after the button click method is completed. What I ended up doing, for the time beeing, is to add

SBox._CumulativeDataRead = 0

in the constructor of the class to ensure that the value is reset upon creation of the object oSBox and this works.

So my question is: Why does .NET "reuse" my old object the 2nd time I click the button?

Please let me know your throughts on this issue and let me know if you need further information from me.

Thanks,
Einar
