1.声明变量

 #region "声明变量"

        /// <summary>
/// 写入INI文件
/// </summary>
/// <param name="section">节点名称[如[TypeName]]</param>
/// <param name="key">键</param>
/// <param name="val">值</param>
/// <param name="filepath">文件路径</param>
/// <returns></returns>
[DllImport("kernel32")]
private static extern long WritePrivateProfileString(string section, string key, string val, string filepath);
/// <summary>
/// 读取INI文件
/// </summary>
/// <param name="section">节点名称</param>
/// <param name="key">键</param>
/// <param name="def">值</param>
/// <param name="retval">stringbulider对象</param>
/// <param name="size">字节大小</param>
/// <param name="filePath">文件路径</param>
/// <returns></returns>
[DllImport("kernel32")]
private static extern int GetPrivateProfileString(string section, string key, string def, StringBuilder retval, int size, string filePath); private string strFilePath = Application.StartupPath + "\\FileConfig.ini";//获取INI文件路径
private string strSec = ""; //INI文件名 #endregion

2.写入到ini文件

 private void WriteIni()
{
try
{
//根据INI文件名设置要写入INI文件的节点名称
//此处的节点名称完全可以根据实际需要进行配置
strSec = Path.GetFileNameWithoutExtension(strFilePath);
WritePrivateProfileString(strSec, "UserName", EDncrypt.MD5Encrypt(txtUser.Text.Trim()), strFilePath);
WritePrivateProfileString(strSec, "Password", EDncrypt.MD5Encrypt(txtPass.Text.Trim()), strFilePath);
WritePrivateProfileString(strSec, "DataBase", EDncrypt.MD5Encrypt(txtDataBase.Text.Trim()), strFilePath);
WritePrivateProfileString(strSec, "Host", EDncrypt.MD5Encrypt(txtServer.Text.Trim()), strFilePath);
MessageBox.Show("写入成功"); }
catch (Exception ex)
{
MessageBox.Show(ex.Message.ToString());
}
}

3.读取ini文件

 private void ReadIni()
{
if (File.Exists(strFilePath))//读取时先要判读INI文件是否存在
{
strSec = Path.GetFileNameWithoutExtension(strFilePath);
txtUser.Text = ContentValue(strSec, "UserName");
txtPass.Text = ContentValue(strSec, "Password");
txtDataBase.Text = ContentValue(strSec, "DataBase");
txtServer.Text = ContentValue(strSec, "Host");
}
else
{
MessageBox.Show("INI文件不存在");
}
}
/// <summary>
/// 自定义读取INI文件中的内容方法
/// </summary>
/// <param name="Section">键</param>
/// <param name="key">值</param>
/// <returns></returns>
private string ContentValue(string Section, string key)
{
StringBuilder temp = new StringBuilder();
GetPrivateProfileString(Section, key, "", temp, , strFilePath);
return EDncrypt.MD5Decrypt(temp.ToString());
}

4.Md5加密与解密类

 public class EDncrypt
{
private static readonly string m_strKey = "dre34ASD";
///MD5加密
public static string MD5Encrypt(string pToEncrypt)
{
DESCryptoServiceProvider des = new DESCryptoServiceProvider();
byte[] inputByteArray = Encoding.Default.GetBytes(pToEncrypt);
des.Key = ASCIIEncoding.ASCII.GetBytes(m_strKey);
des.IV = ASCIIEncoding.ASCII.GetBytes(m_strKey);
MemoryStream ms = new MemoryStream();
CryptoStream cs = new CryptoStream(ms, des.CreateEncryptor(), CryptoStreamMode.Write);
cs.Write(inputByteArray, , inputByteArray.Length);
cs.FlushFinalBlock();
StringBuilder ret = new StringBuilder();
foreach (byte b in ms.ToArray())
{
ret.AppendFormat("{0:X2}", b);
}
ret.ToString();
return ret.ToString();
} ///MD5解密
public static string MD5Decrypt(string pToDecrypt)
{
DESCryptoServiceProvider des = new DESCryptoServiceProvider();
byte[] inputByteArray = new byte[pToDecrypt.Length / ];
for (int x = ; x < pToDecrypt.Length / ; x++)
{
int i = (System.Convert.ToInt32(pToDecrypt.Substring(x * , ), ));
inputByteArray[x] = (byte)i;
} des.Key = ASCIIEncoding.ASCII.GetBytes(m_strKey);
des.IV = ASCIIEncoding.ASCII.GetBytes(m_strKey);
MemoryStream ms = new MemoryStream();
CryptoStream cs = new CryptoStream(ms, des.CreateDecryptor(), CryptoStreamMode.Write);
cs.Write(inputByteArray, , inputByteArray.Length);
cs.FlushFinalBlock(); StringBuilder ret = new StringBuilder();
return System.Text.Encoding.Default.GetString(ms.ToArray());
}
}
