C # Workaround for passing multiple parameters to a thread (two kinds) _c# tutorial

Problem:

For multithreaded programming, it is often necessary to pass more than one parameter to a thread, while a thread in C # receives only 1 parameters of type object (as follows):

Thread t = new Thread (new Parameterizedthreadstart (Newthread));
T.start (parameter);
void Newthread (object)
{
...}, ...
}

And now you need to pass multiple parameters to the thread, such as method methods that want to run with a separate thread

void method (int begin,int end) {..........
}

Workaround 1: Create a new class for the Run method

class MyClass
{
private int begin;
public int begin
{
set{this.begin=value}
}
private int end;
public int end
{
set{this.end=value;}
}
Public run ()
{method
(begin,end);
}
Private method (int begin,int end)
{
...
}... ...}

Then create a new instance of the class, after assigning the value can run, the code is as follows;

MyClass C = new MyClass ();
c.begin=100;
c.end=10000;
Thread t = new Thread (new ThreadStart (C.run))
T.start ();

2, Workaround 2: The array or collection instance as arguments passed in

is currently doing a multithreaded software, used in this section, feel every time to create a new class, more trouble, check the online mainstream is the solution to the method 1, and then I figured out another way, even though the new thread can only pass 1 parameters to go in, but we can pass a set or the parameters of the array class to go in, This solves the problem of passing multiple parameters to a new thread at once.

Similarly, for the method above, you need to pass 2 integers of type int, first add an overload of method methods

void method (Object o)
{
//Here the incoming parameters are processed
int[] p = (int[]) o;
Invokes the original methods method
(P[0],p[1]);

The parameters to be passed are stored in arrays or collections

int Para[]=new int[2]{100,10000};

The last new thread is called

Thread t = new Thread (new Parameterizedthreadstart (method))
T.start (para);

This allows the 2 parameters to be passed into the thread.

The parameter types passed can also be used in list<> or other collections, and the types of these arguments passed in are the same, and for different types, they can be considered in the form of list<object> or object[]. The parameters are processed in the overloaded method.

The above is a small set to the introduction of C # to the thread to pass multiple parameters of the solution (two kinds), I hope to help you, if you have any questions please give me a message, small series will promptly reply to everyone.
