  • 用C#读取,写入ini文件

           [DllImport("kernel32.dll")]
            private static extern bool WritePrivateProfileString(string section, string key, string val, string filePath);
            [DllImport("kernel32.dll")]
            private static extern int GetPrivateProfileString(string section, string key, string def, StringBuilder retVal, int size, string filePath);
            private string sPath_ = "";
            /// <summary>
            /// 绝对路径
            /// </summary>
            public string sPath
            {
                get { return sPath_; }
                set { sPath_ = value; }
            }
    
            /// <summary>

            /// <param name="section">文件域</param>
            /// <param name="key">key值</param>
            /// <param name="value">value值</param>
            /// <returns></returns>
            public bool WriteToIni(string section, string key, string value)
            {
                bool result = false;
                if (System.IO.File.Exists(sPath))
                {
                    result = WritePrivateProfileString(section, key, value, sPath);
                }
                return result;
            }
    
            /// <summary>
            /// 从ini文件进行读取
            /// </summary>
            /// <param name="section">文件域</param>
            /// <param name="key">key值</param>
            /// <param name="defaultValue">默认值</param>
            /// <returns></returns>
            public string ReadFromIni(string section, string key, string defaultValue = "")
            {
                string result = defaultValue;
                if (System.IO.File.Exists(sPath))
                {
                    StringBuilder sTemp = new StringBuilder(1024);
                    int i = GetPrivateProfileString(section, key, defaultValue, sTemp, 1024, sPath);
                    result = sTemp.ToString();
                }
                return result;
            }
    

    强烈注意:

    ini文件必须为ANSI、Unicode 格式,否则会出现异常,至于原因暂时没有找到。请大侠帮忙解释。
