C# winfrom中创建,读,写ini文件

一个用C#写Ini文件的一个数，和大家分享：

using System; using System.Collections.Generic; using System.Text; using System.Runtime.InteropServices; using System.IO; using System.Security.Cryptography; public class WriteIniFile { private string strKey = "GZ530@%@!"; public string strinipath; [DllImport("kernel32")] private static extern long WritePrivateProfileString(string StrProjcetName, string skey, string sval, string sfilePath); [DllImport("kernel32")] private static extern int GetPrivateProfileString(string StrProjcetName, string skey, string sdef, StringBuilder retVal, int Intsize, string sfilePath); ///

/// 构造方法 ///

/// 文件路径 public WriteIniFile(string INIPath) { strinipath = INIPath; } ///

/// 写入INI文件 ///

/// 项目名称(如 [MyProjectName] ) /// 键 /// 值 public void IniWriteValue(string StrProjcetName, string skey, string StrValue) { WritePrivateProfileString(StrProjcetName, skey, StrValue, this.strinipath); } ///

/// Md5加密写入INI文件 ///

/// 项目名称(如 [MyProjectName] ) /// 键 /// 值 public void IniMd5WriteValue(string StrProjcetName, string skey, string StrValue) { string str = MD5Encrypt(StrValue, strKey); WritePrivateProfileString(StrProjcetName, skey, str, this.strinipath); } ///

/// 读出INI文件 ///

/// 项目名称(如 [MyProjectName] ) /// 键 public string IniReadValue(string StrProjcetName, string skey) { StringBuilder temp = new StringBuilder(500); int i = GetPrivateProfileString(StrProjcetName, skey, "", temp, 500, this.strinipath); return temp.ToString(); } ///

/// 读出INI文件 ///

/// 项目名称(如 [MyProjectName] ) /// 键 public string IniMd5ReadValue(string StrProjcetName, string skey) { StringBuilder temp = new StringBuilder(500); int i = GetPrivateProfileString(StrProjcetName, skey, "", temp, 500, this.strinipath); string str = temp.ToString(); return MD5Decrypt(str, strKey); } ///

/// 验证文件是否存在 ///

/// 布尔值 public bool ExistINIFile() { return File.Exists(strinipath); } ///

/// 带参数的MD5加密 ///

/// /// /// public string MD5Encrypt(string spToEncrypt, string sKey) { DESCryptoServiceProvider des = new DESCryptoServiceProvider(); byte[] inputByteArray = Encoding.Default.GetBytes(spToEncrypt); des.skey = ASCIIEncoding.ASCII.GetBytes(sKey); des.IV = ASCIIEncoding.ASCII.GetBytes(sKey); MemoryStream ms = new MemoryStream(); CryptoStream cs = new CryptoStream(ms, des.CreateEncryptor(), CryptoStreamMode.Write); cs.Write(inputByteArray, 0, inputByteArray.Length); cs.FlushFinalBlock(); StringBuilder ret = new StringBuilder(); foreach (byte b in ms.ToArray()) { ret.AppendFormat("{0:X2}", b); } ret.ToString(); return ret.ToString(); } ///

/// 带参数的MD5解密 ///

/// /// /// public string MD5Decrypt(string spToDecrypt, string sKey) { DESCryptoServiceProvider des = new DESCryptoServiceProvider(); byte[] inputByteArray = new byte[spToDecrypt.Length / 2]; for (int x = 0; x < spToDecrypt.Length / 2; x++) { int i = (Convert.ToInt32(spToDecrypt.Substring(x * 2, 2), 16)); inputByteArray[x] = (byte)i; } des.skey = ASCIIEncoding.ASCII.GetBytes(sKey); des.IV = ASCIIEncoding.ASCII.GetBytes(sKey); MemoryStream ms = new MemoryStream(); CryptoStream cs = new CryptoStream(ms, des.CreateDecryptor(), CryptoStreamMode.Write); cs.Write(inputByteArray, 0, inputByteArray.Length); cs.FlushFinalBlock(); StringBuilder ret = new StringBuilder(); return System.Text.Encoding.Default.GetString(ms.ToArray()); } }
