INI文件读写

废话不多说 直接切入主题上代码

using System; using System.Collections.Generic; using System.Linq; using System.Runtime.InteropServices; using System.Text; using System.Threading.Tasks; namespace DemoFiles { /// <summary> /// INI文件读写类。 /// </summary> public class INIFile { /** [xxx] a=a ;这里是a的注释 **/ public string path; public INIFile(string INIPath) { //IniPath路径必须为绝对路径，不然有可能读取/保存，不出值。 path = INIPath; } [DllImport("kernel32")] private static extern long WritePrivateProfileString(string section, string key, string val, string filePath); [DllImport("kernel32")] private static extern int GetPrivateProfileString(string section, string key, string def, StringBuilder retVal, int size, string filePath); [DllImport("kernel32")] private static extern int GetPrivateProfileString(string section, string key, string defVal, Byte[] retVal, int size, string filePath); /// <summary> /// 写INI文件 /// </summary> /// <param name="Section">项目名称</param> /// <param name="Key">键</param> /// <param name="Value">值</param> public void IniWriteValue(string Section, string Key, string Value) { WritePrivateProfileString(Section, Key, Value, this.path); } /// <summary> /// 读取INI文件 /// </summary> /// <param name="Section">项目名称</param> /// <param name="Key">键</param> /// <returns></returns> public string IniReadValue(string Section, string Key) { StringBuilder temp = new StringBuilder(255); int i = GetPrivateProfileString(Section, Key, "", temp, 255, this.path); return temp.ToString(); } public byte[] IniReadValues(string section, string key) { byte[] temp = new byte[255]; int i = GetPrivateProfileString(section, key, "", temp, 255, this.path); return temp; } /// <summary> /// 删除ini文件下所有段落 /// </summary> public void ClearAllSection() { IniWriteValue(null, null, null); } /// <summary> /// 删除ini文件下personal段落下的所有键 /// </summary> /// <param name="Section"></param> public void ClearSection(string Section) { IniWriteValue(Section, null, null); } } }
