C# ini文件操作

        //文件INI名稱
        private string m_iniPath;
        ////聲明讀寫INI文件的API函數
        [DllImport("kernel32")]

            int i = GetPrivateProfileString(Section, Key, "", temp, 255, this.m_iniPath);
            return temp.ToString();
        }
    }
 
 
//寫ini文件
   string picPath = Application.StartupPath + @"\config.ini";
   string newLocation = (folderBrowserDialog1.SelectedPath + @"\");//用戶通過folderbrowserdialog選擇的路徑
   ClsIni ci = new ClsIni(picPath);
    ci.IniWriteValue("PhotoLocation", "path", newLocation);
寫入後的格式
[PhotoLocation]
path=E:\\

//讀ini文件
ci.IniReadValue("PhotoLocation", "path");
