problem disposing class in Dictionary it is Still in the heap memory although using GC.Collect
- by Bahgat Mashaly
Hello
i have a problem disposing class in Dictionary
this is my code
private Dictionary<string, MyProcessor> Processors = new Dictionary<string, MyProcessor>();
private void button1_Click(object sender, EventArgs e)
{
if (!Processors.ContainsKey(textBox1.Text))
{
Processors.Add(textBox1.Text, new MyProcessor());
}
}
private void button2_Click(object sender, EventArgs e)
{
MyProcessor currnt_processor = Processors[textBox1.Text];
Processors.Remove(textBox2.Text);
currnt_processor.Dispose();
currnt_processor = null;
GC.Collect();
}
public class MyProcessor: IDisposable
{
private bool isDisposed = false;
string x = "";
public MyProcessor()
{
for (int i = 0; i < 20000; i++)
{
//this line only to increase the memory usage to know if the class is dispose or not
x = x + "gggggggggggg";
}
this.Dispose();
GC.SuppressFinalize(this);
}
public void Dispose()
{
this.Dispose(true);
GC.SuppressFinalize(this);
}
public void Dispose(bool disposing)
{
if (!this.isDisposed)
{
isDisposed = true;
this.Dispose();
}
}
~MyProcessor()
{
Dispose(false);
}
}
i use "ANTS Memory Profiler" to monitor heap memory
the disposing work only when i remove all keys from dictionary
how can i destroy the class from heap memory ?
thanks in advance
