c# force call static function with default value instead of non-static
0
I have an object to manage ini files.
I concept this object to bee used in two ways: static and non-static. So I can call IniFile.Read directly when I just need a value or I can instantiate IniFile Object and do some operations. All non-static functions call static equivalent one, myIniFile.Read(sectionName, value, defaultValue) calls IniFile.Read(iniPath, sectionName, value, defaultValue).
Read() function has default value for the last parameter.
My problem is when I call IniFile.Read() function, compiler doesn't know if I call the static function or the other one. Is there a way to resolve this problem ?
public static string ReadValue(string filePath, string section, string key, string defaultValue="")
public string ReadValue(string Section, string Key, string defaultValue="")

As @Skogandr says, you would need to instantiate the class, and call it from the instantiated variable. For example, var iniFile = new InitFile(); iniFile.ReadValue(...

public void InstanceCallSite()
{

// or in the general case: someInstance.ReadValue("a", "b", "c");

}
public static void StaticCallSite()
{

public static string ReadValue(string filePath, string section, string key, string defaultValue = "")
{
Console.WriteLine("static");
return "";
}
public string ReadValue(string Section, string Key, string defaultValue = "")
{
Console.WriteLine("instance");
return "";
}
The InstanceCallSite usage outputs:
