利用.Net的C#做了一个登录的页面，里面包含了注册。注册使用点击按钮跳转到注册页面，在账号密码上面输入的信息读取到ini文件中
给大家看下这个是登录页面的代码：
using System;
using System.Collections;
using System.Windows.Forms;
using System.Configuration;
using Login;
namespace Demo
{
public partial class two : Form
{
IniFiles ini = new IniFiles(Application.StartupPath + @"\MyConfig.INI");
public two()
{
InitializeComponent();
}
//载入事件
private void two_Load(object sender, EventArgs e)
{
user_name.Text = IniFiles.ReadString("Login", "username");
if (ConfigurationManager.AppSettings["rememberme"].Equals("true"))
{
password.Text = ConfigurationManager.AppSettings["password"];
remember.Checked = true;
}
}
private void sign_in_Click(object sender, EventArgs e)
{
this.Hide();
one no = new one();
no.ShowDialog();
Configuration cfa = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
if (automatic.Checked)
{
cfa.AppSettings.Settings["autologin"].Value = "trye";
cfa.AppSettings.Settings["rememberme"].Value = "true";
cfa.AppSettings.Settings["name"].Value = user_name.Text;
cfa.AppSettings.Settings["password"].Value = password.Text;
cfa.Save();
}
else
{
if (remember.Checked)
{
cfa.AppSettings.Settings["autologin"].Value = "false";
cfa.AppSettings.Settings["rememberme"].Value = "false";
cfa.AppSettings.Settings["name"].Value = "";
cfa.AppSettings.Settings["password"].Value = "";
}
}
// cfa.Save();
}
private void close_Click(object sender, EventArgs e)
{
Close();
}
//本文框是否有文本
private Boolean textboxHasText = false;
private void user_name_Leave(object sender, EventArgs e)
{
if (string.IsNullOrEmpty(user_name.Text))
{
lb_name.Text = "用户名是必填项";
}
else
{
lb_name.Text = "";
}
}
private void user_name_SelectedIndexChanged(object sender, EventArgs e)
{
}
private void automatic_CheckedChanged(object sender, EventArgs e)
{
}
private void register_Click(object sender, EventArgs e)
{
this.Hide();
three th = new three();
th.ShowDialog();
}
}
}
然后我又创建了一个IniFiles的类里面的代码也给大家看一下
using System;
using System.Text;
using System.Collections.Specialized;
using System.IO;
using System.Runtime.InteropServices;
namespace Login
{
public class IniFiles
{
public static string FileName; //INI文件名
//string path = System.IO.Path.Combine(Application.StartupPath, "新建文本文档.ini");
#region 声明读写INI文件的API函数
[DllImport("kernel32")]
private static extern bool WritePrivateProfileString(string section, string key, string val, string filePath);
[DllImport("kernel32")]
private static extern int GetPrivateProfileString(string section, string key, string def, byte[] retVal, int size, string filePath);
#endregion
#region 类的构造函数，传递INI文件名
public IniFiles(string AFileName)
{
// 判断文件是否存在
FileInfo fileInfo = new FileInfo(AFileName);
//Todo:搞清枚举的用法
if ((!fileInfo.Exists))
{ //|| (FileAttributes.Directory in fileInfo.Attributes))
//文件不存在，建立文件
System.IO.StreamWriter sw = new System.IO.StreamWriter(AFileName, false, System.Text.Encoding.Default);
try
{
sw.Write("#表格配置档案");
sw.Close();
}
catch
{
throw (new ApplicationException("Ini文件不存在"));
}
}
//必须是完全路径，不能是相对路径
FileName = fileInfo.FullName;
}
#endregion
#region 写INI文件
public static void WriteString(string Section, string Key, string Value)
{
if (!WritePrivateProfileString(Section, Key, Value, FileName))
{
throw (new ApplicationException("写Ini文件出错"));
}
}
#endregion
#region 读取INI文件指定
public static string ReadString(string Section, string Key)
{
Byte[] Buffer = new Byte[65535];
int bufLen = GetPrivateProfileString(Section, Key, "", Buffer, Buffer.GetUpperBound(0), FileName);
//必须设定0（系统默认的代码页）的编码方式，否则无法支持中文
string s = Encoding.GetEncoding(0).GetString(Buffer);
s = s.Substring(0, bufLen);
return s.Trim();
}
#endregion
}
}
并且在C:\Users\PXNB\source\repos\Demo\Demo\bin\Debug下面创建了一个MyConfig.ini的一个记事本
对了还有一个注册的页面代码也给大家
using Login;
using System;
using System.Windows.Forms;
namespace Demo
{
public partial class three : Form
{
two tw = new two();
public three()
{
InitializeComponent();
}
private void three_Load(object sender, EventArgs e)
{
}
private void confirm_Click(object sender, EventArgs e)
{
this.Hide();
two tw = new two();
tw.ShowDialog();
}
private void username_Leave(object sender, EventArgs e)
{
if (string.IsNullOrEmpty(username.Text))
{
tet_username.Text = "用户名不能是空";
}
else
{
tet_username.Text = "";
}
}
private void password_Leave(object sender, EventArgs e)
{
if (string.IsNullOrEmpty(password.Text))
{
tet_password.Text = "密码不能是空";
}
else
{
tet_password.Text = "";
}
}
private void confirm_password_Leave(object sender, EventArgs e)
{
if (string.IsNullOrEmpty(confirm_password.Text))
{
tet_confirm_password.Text = "两次密码输入不一致";
}
else
{
tet_confirm_password.Text = "";
}
}
}
}
完全是从java转到C#的不是很懂C#虽然很多地方很像但是还是吃不透
能思路清晰一下，最好能附带上自己的代码麻烦了
有什么问题吗
检查你的 IniFiles，是否抄错了
没报错而是空的话检查一下传到GetPrivateProfileString的参数是不是都正确呢
