调用Config.ini类

private static string sPath = @Directory.GetCurrentDirectory() + "\\config.ini";
[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);

public static void Writue(string section, string key, string value)
{
// section=配置节，key=键名，value=键值，path=路径
WritePrivateProfileString(section, key, value, sPath);
}

public static string ReadValue(string section, string key)
{
// 每次从ini中读取多少字节
System.Text.StringBuilder temp = new System.Text.StringBuilder(255);
// section=配置节，key=键名，temp=上面，path=路径
GetPrivateProfileString(section, key, "", temp, 255, sPath);
return temp.ToString(); //注意类型的转换
}

比如

int Forecast = Convert.ToInt32(iniSet.ReadValue("1", "1"));
