This error occurs if you are passing an argument to a function that takes a ref or out parameter and you dont include the ref or out keyword at the point of call or you include the wrong keyword. A ref argument can be read and written to. To use a ref parameter both the method definition and the calling method must explicitly use the ref keyword as shown in the following example. If you dont want to put the data you can use the Out parameter. Argument number must be passed with the keyword keyword. Note that objects passed by value are sharing the same data on the heap so any change to propertiesfields of the object will also be seen by the caller as if they were passed by ref. A ref argument can be read and written to. It is not compulsory to initialize a parameter or argument before it is passed to an out. The error text indicates the appropriate keyword to use and which argument caused the failure. To resolve this error remove the incorrect keyword and use the appropriate keyword that matches the function declaration if any.

The effect of passing by reference is that any change to the parameter in the called method is reflected in the calling method So it becomes very important to decide whether we want to use the ref or out keyword especially when the parameter types are value types. The declaration of ref or out must be in the function header AND the call to the function.

But if you pass obj1 as SomeMethod2 ref obj1 then after SomeMethod2 the obj1 maynot contain 1021 provided you do something like obj1 new C1 inside SomeMethod2.
Declaring a method with out arguments is a. CmdParametersAddGroupI d OracleDbTypeDecimalValu e DataCheckerConvertNullabl eIntegerVa lue ref thisGroupId. This means we can assign the parameter in the called method and have it also be assigned at the calling site.
The in keyword cannot be used on any generic type even when constrained to be a struct. In argument may not be passed with the ref keyword. The ref keyword cannot be used on the first argument of an extension method when the argument is not a struct or a generic type not constrained to be a struct.
