在读写的时候可以使用静态方法 例：

static INIClass m_IniFileUserOption = null;

public static string ReadOptionUser(string sSectiong, string sKey)

{

if (m_IniFileUserOption == null) return "";

string strValue = m_IniFileUserOption.IniReadValue(sSectiong, sKey);

return strValue;

}

public static void WriteOptionUser(string sSectiong, string sKey, object objValue)

{

if (m_IniFileUserOption == null) return;

// string strValue = Cryptogram.EncryptDES(objValue.ToString(), "Ki8kQi9p");

m_IniFileUserOption.IniWriteValue(sSectiong, sKey, objValue);

}
