Question

If I want to insert into a database column of type char(2) from C#.
What data type would I use in C#?

If using the following code:

private static SqlParameter addParameterValue(string parameterName, ? parameterValue, SqlCommand command)
    {
        SqlParameter parameter = new SqlParameter(parameterName, SqlDbType.Char);
        parameter.Value = parameterValue;
        command.Parameters.Add(parameter);
        return parameter;
    }

What type would I give to parameterValue?

I already have method like this when the parameterValue is of type string, so this could be a problem when telling the difference between SqlDbType.Char and SqlDbType.Varchar

Answer 1

string will work fine if it is 2 characters or shorter
