不同的主要入口点

问题描述

如果我将此项目添加到顶部，所有错误都会消失，但是.exe实际上不会执行任何操作.

If I add this top my project all errors go away, but the .exe doesn't actually do anything.

[STAThread]
静态void Main()
{
}

[STAThread]
static void Main()
{
}

如果我取出来并使用它:

If I take that out and use this:

private void Main(string [] args)
{
DateTime dt = DateTime.Today.AddDays(-1);
字符串日期= String.Format(" {0:yyyyMMdd}，dt);
getFTPFile("raw_CA _" +日期+".txt");
getFTPFile("raw_EM _" +日期+".txt");
getFTPFile("raw_GLB _" +日期+".txt");
getFTPFile("raw_US _" +日期+".txt");
}

private void Main(string[] args)
{
DateTime dt = DateTime.Today.AddDays(-1);
string date = String.Format("{0:yyyyMMdd}", dt);
getFTPFile("raw_CA_" + date + ".txt");
getFTPFile("raw_EM_" + date + ".txt");
getFTPFile("raw_GLB_" + date + ".txt");
getFTPFile("raw_US_" + date + ".txt");
}

然后我收到以下错误消息.

Then I get the following error.

ConsoleApplication1.exe"不包含适用于入口点的静态"Main"方法.   ConsoleApplication1

ConsoleApplication1.exe' does not contain a static 'Main' method suitable for an entry point    ConsoleApplication1

最后，如果我将其设置为静态，就像这样.

Finally, if I make it static, like this.

static void Main(string [] args)
{
DateTime dt = DateTime.Today.AddDays(-1);
字符串日期= String.Format("{{:yyyyMMdd}"，dt);
getFTPFile("raw_CA _" +日期+".txt");
getFTPFile("raw_EM _" +日期+".txt");
getFTPFile("raw_GLB _" +日期+".txt");
getFTPFile("raw_US _" +日期+".txt");
}

static void Main(string[] args)
{
DateTime dt = DateTime.Today.AddDays(-1);
string date = String.Format("{0:yyyyMMdd}", dt);
getFTPFile("raw_CA_" + date + ".txt");
getFTPFile("raw_EM_" + date + ".txt");
getFTPFile("raw_GLB_" + date + ".txt");
getFTPFile("raw_US_" + date + ".txt");
}

非静态字段，方法或属性'ConsoleApplication1.Program.getFTPFile(string)'需要对象引用

An object reference is required for the non-static field, method, or property 'ConsoleApplication1.Program.getFTPFile(string)'

最后，我想到了这个.

public static void Main(string [] args)
{
DateTime dt = DateTime.Today.AddDays(-1);
字符串日期= String.Format(" {0:yyyyMMdd}，dt);
程序p = new Program();
p.getFTPFile("raw_CA_" +日期+".txt");
p.getFTPFile("raw_EM _" +日期+".txt");
p.getFTPFile("raw_GLB _" +日期+".txt");
p.getFTPFile("raw_US_" +日期+".txt");
}

public static void Main(string[] args)
{
DateTime dt = DateTime.Today.AddDays(-1);
string date = String.Format("{0:yyyyMMdd}", dt);
Program p = new Program();
p.getFTPFile("raw_CA_" + date + ".txt");
p.getFTPFile("raw_EM_" + date + ".txt");
p.getFTPFile("raw_GLB_" + date + ".txt");
p.getFTPFile("raw_US_" + date + ".txt");
}

现在，所有编译错误都消失了，但是出现了运行时错误.有人可以在这里解释我在做什么错吗?

Now, all compile errors are gone, but there is a run-time error.  Can someone please explain what I'm doing wrong here?

知识是我唯一可以给您的东西，并且仍然保留下来，我们俩对此都比较满意.

Knowledge is the only thing that I can give you, and still retain, and we are both better off for it.

推荐答案

示例:

static void Main(params string[] args)
{
    if (args.Any())
    {
        // Do code that references args
    }
    else
    {
        // Do code that depends on no input arguments.
    }
}
