Thread
suggest changeSee below for a simple example of how to use a Thread
to do some time intensive stuff in a background process.
public async void ProcessDataAsync()
{
// Start the time intensive method
Thread t = new Thread(TimeintensiveMethod);
// Control returns here before TimeintensiveMethod returns
Console.WriteLine("You can read this while TimeintensiveMethod is still running.");
}
private void TimeintensiveMethod()
{
Console.WriteLine("Start TimeintensiveMethod.");
// Do some time intensive calculations...
using (StreamReader reader = new StreamReader(@"PATH_TO_SOME_FILE"))
{
string v = reader.ReadToEnd();
for (int i = 0; i < 10000; i++)
v.GetHashCode();
}
Console.WriteLine("End TimeintensiveMethod.");
}
As you can see we can not return a value from our TimeIntensiveMethod
because Thread
expects a void Method as its parameter.
To get a return value from a Thread
use either an event or the following:
int ret;
Thread t= new Thread(() =>
{
Console.WriteLine("Start TimeintensiveMethod.");
// Do some time intensive calculations...
using (StreamReader reader = new StreamReader(file))
{
string s = reader.ReadToEnd();
for (int i = 0; i < 10000; i++)
s.GetHashCode();
}
Console.WriteLine("End TimeintensiveMethod.");
// return something to demonstrate the coolness of await-async
ret = new Random().Next(100);
});
t.Start();
t.Join(1000);
Console.Writeline("Count: " + ret);
Found a mistake? Have a question or improvement idea?
Let me know.
