how to implement class with collection of string/object pairs so that an object can be returned with
- by matti
The values in a file are read as string and can be double, string or int or maybe even lists. An example file:
DatabaseName=SomeBase
Classes=11;12;13
IntValue=3 //this is required!
DoubleValue=4.0
I was thinking something like this:
public static T GetConfigValue(string cfgName)
{
// here we just return for example the value which could
// be List[int] if parameter cfgName='Classes'
// and LoadConfig was called with Dictionary containing
// keyvaluepair 'Classes' / typeof(List[int])
}
public static bool LoadConfig(Dictionary reqSettings,
Dictionary optSettings)
{
foreach (KeyValuePair kvPair in reqSettings)
{
if (ReadCheckAndStore(kVPair, true))
return false;
}
foreach (KeyValuePair kvPair in reqSettings)
{
if (ReadCheckAndStore(kVPair, false))
return false;
}
return true;
}
private static bool ReadCheckAndStore(KeyValuePair kVPair, bool isRequired)
{
if (!ReadValue(kVPair.Key, out confValue) && isRequired) //req. IntValue !found
return false;
//here also have to test if read value is wanted type.
//and if yes store to collection.
}
Thanks a lot & BR! -Matti
PS. Additional issue is default values for optional settings. It's not elegant to pass them to LoadConfig in separate Dictionary, but that is an other issue...
