c# - 按顺序运行任务

Question

我有五个 Windows 服务。我按顺序运行服务。

if(a_Condition)
{ 
     services[0] = new Processing_0();
// blah blah
}
if(b_Condition)
{
    service[1] = new Processing_1();
// blah blah
}
if(c_Condition)
{
    service[2] = new Processing_2();
// blah blah
}
if(d_Condition)
{
    service[3] = new Processing_3();
// blah blah
}
if(e_Condition)
{
    service[4] = new Processing_4();
// blah blah
}

出于某种原因，我想使用任务，代码是：

Task.StartNew(() => {
if (a_Condition) { var x = new Processing_0(); ... }
})
.ContinueWith(() => {
if (b_Condition) { var x = new Processing_1(); ... }
})
.ContinueWith(() => {
if (c_Condition) { var x = new Processing_2(); ... }
}) 
.ContinueWith(() => {
if (d_Condition) { var x = new Processing_3(); ... }
})
.ContinueWith(() => {
if (e_Condition) { var x = new Processing_4(); ... }
});

可以吗？
