如何用C#解决语法问题？

好的，我一直在回避一些语法问题（

一个是在类型或名称空间定义的末尾，或者是预期的文件结尾

另一个是在

private static void OnTimedEvent1（对象源，ElapsedEventArgs e）

的一半处，带有{expected}

谢谢

实际代码：（我也把错误放在这里）

在另一个方法中有一个方法

    private static void OnTimedEvent1(object source, ElapsedEventArgs e) 
    { // { expected here 
        public static string TextToBase64(string sAscii)

这可能就是您正在尝试执行的操作--您希望从事件处理程序中调用

CheckMail（）

using System;
using System.Net;
using System.Timers;
using System.Xml;

namespace Gmail_final_prep 
{ 
public class Gmail_FP 
{ 
    private static System.Timers.Timer gTimer; 

    public static void GMain() 
    { 
        gTimer = new System.Timers.Timer(2000); 

        // Hook up the Elapsed event for the timer. 
        gTimer.Elapsed += OnTimedEvent1; 

        gTimer.Interval = 2000; 
        gTimer.Enabled = true; 

        Console.WriteLine("Press the Enter key to exit the program."); 
        Console.ReadLine(); 

        // If the timer is declared in a long-running method, use 
        // KeepAlive to prevent garbage collection from occurring 
        // before the method ends. 
        //GC.KeepAlive(gTimer); 
    } 

    private static void OnTimedEvent1(object source, ElapsedEventArgs e) 
    { // { expected here 
        CheckMail();
    }

    public static string TextToBase64(string sAscii)
    {
        System.Text.ASCIIEncoding encoding = new System.Text.ASCIIEncoding();
        byte[] bytes = encoding.GetBytes(sAscii);
        return System.Convert.ToBase64String(bytes, 0, bytes.Length);
    }

    public static string CheckMail()
    {
        string result = "0";

        try
        {
            var url = @"https://gmail.google.com/gmail/feed/atom";
            var USER = "usr";
            var PASS = "pss";

            var encoded = TextToBase64(USER + ":" + PASS);

            var myWebRequest = HttpWebRequest.Create(url);
            myWebRequest.Method = "POST";
            myWebRequest.ContentLength = 0;
            myWebRequest.Headers.Add("Authorization", "Basic " + encoded);

            var response = myWebRequest.GetResponse();
            var stream = response.GetResponseStream();

            XmlReader reader = XmlReader.Create(stream);
            System.Text.StringBuilder gml = new System.Text.StringBuilder();
            while (reader.Read())
            {
                if (reader.NodeType == XmlNodeType.Element)
                    if (reader.Name == "fullcount")
                    {
                        gml.Append(reader.ReadElementContentAsString()).Append(",");
                        //result = reader.ReadElementContentAsString(); 
                        //return result; 
                    }
            }
            Console.WriteLine(gml.ToString());
        }
        catch (Exception ee) { Console.WriteLine(ee.Message); }
        return result;
    } 
} 
} // Type or namespace definition, or end-of-file expected here

这是不合法的——您不能将一种方法嵌入另一种方法。

我想知道这部分在做什么：

private static void OnTimedEvent1(object source, ElapsedEventArgs e)
{ // { expected here
     public static string TextToBase64(string sAscii)

你的问题可能就在这里。

哇，谢谢！我不知道我怎么会错过这个（改为在eventhandler中调用它），但是我又一次错过了一个方法中的方法…非常感谢！

    private static void OnTimedEvent1(object source, ElapsedEventArgs e)
    { // { expected here
        public static string TextToBase64(string sAscii)
        {

private static void OnTimedEvent1(object source, ElapsedEventArgs e)
{ // { expected here
     public static string TextToBase64(string sAscii)
