dataFile["admins", player.UserIDString, "Admin"] = "true"
dataFile.Save();​

and then using an if statement to check it

if(dataFile["admins", player.UserIDString, "Admin"] == "true")
{

}

which seems to work perfectly well until you restart the server which it then goes past all of my if statements and does nothing even if its checking if it is null.
The only way i have found to fix it is to clear the datafile but at the same time that really isnt a fix.

DynamicConfigFile dataFile = Interface.Oxide.DataFileSystem.GetDatafile("Aquatic")

Error while compiling: Aquatic.cs(108,25): error CS0019: Operator `==' cannot be applied to operands of type `object' and `bool'

im quite sure im reading the file considering it works fine without the plugin reloading unless you can tell me otherwise and i am using the code below to define dataFile

DynamicConfigFile dataFile = Interface.Oxide.DataFileSystem.GetDatafile("Aquatic")

and im using a string instead of a boolean due to the if statement not liking me using a boolean as it errors with this:

Error while compiling: Aquatic.cs(108,25): error CS0019: Operator `==' cannot be applied to operands of type `object' and `bool'

ok, i have done that now and that seems to have fixed it
but i dont really get why it fixed that

The way you did it initially was wrong. If you are sure about variable type you should typecast it to avoid errors. Also I do not recommend to work with indexers in datafile, it's less error-prone to create a custom class and (de)serialize it with DynamicConfigFile.(Read/Write)Object<T>(string)
