4.0版

public static T Execute<T>(Func<T> func, int timeout)
{
    T result;
    TryExecute(func, timeout, out result);
    return result;
}

public static bool TryExecute<T>(Func<T> func, int timeout, out T result)
{
    var t = default(T);
    var thread = new Thread(() => t = func());
    thread.Start();
    var completed = thread.Join(timeout);
    if (!completed) thread.Abort();
    result = t;
    return completed;
}

public delegate object ExecuteMethod(object parameter);
public static object Execute(ExecuteMethod executeMethod, object parameter, int timeout)
{
    object result;
    TryExecute(executeMethod, parameter, timeout, out result);
    return result;
}

public static bool TryExecute(ExecuteMethod executeMethod,object parameter, int timeout, out object result)
{
    object r=null;
    var thread = new Thread(() => r = executeMethod(parameter));
    thread.Start();
    var completed = thread.Join(timeout);
    if (!completed) thread.Abort();
    result = r;
    return completed;
}
