I ran into a bug that was bothering me. I had JObject that I thought would be fine with
obj["role"].ToString()
The string was there and everything. A final resort was to change to a
(string)obj["role"]
just to see what happens and it works. My question is how do I know when to use a .ToString() as opposed to a (string) as opposed to an "as String".

I have project in development where string operations like "Hi " + variable + ", welcome to Project" are used at many places (given example is very minor one).
One of the requirement is to convert it to string.format style.
It is very long and tedious job, where I would not like to break earlier working code due to any human error might happen while converting it.
I would like to if any Macro or VS command which I can create to handle it. Just like we mark block of code and do Extract function in Re-factor options.

}

This second line is error and i need the result in the specified format or same format as in the published date but in local time ie IST (India Standard Time)
I have a string I need to convert back to a date. I can call .ToString("yyyyMMdd") and get the string i want. My question is how can I convert that back into a date? I'm trying something like the following with no luck.
DateTime d;
var formatInfo = new DateTimeFormatInfo {ShortDatePattern = "yyyyMMdd"};
if (DateTime.TryParse(details.DetectionTime.Date, formatInfo, DateTimeStyles.None, out d))
{
lit.Text = d.ToShortTimeString(); //would like 07/30/2010 as the text
}
I've never used DateTimeFormatInfo before if that isn't obvious. Can someone point me in the right direction. I know I could probably use substring and create a new DateTime(y, m, d) etc... I'm just wondering since c# interpreted .ToString() correctly, if it can't derive a date from the very same string it output.

View 4 Repliesi have two tables which are related (school and departments). school_table (school_id, school_name) and department (dept_id, dept_name, school_id). page 1 creates the school - i take school name via textbox and school_id is auto generated in database. so informatics = 1, science = 2, etc page2 creates department - i take department name via textbox, dept_id is auto generated, and now i need a way to take school_id from this page to create the relationships (so we know which department belongs to which school). however, i don't really want the user to enter school Id that gets auto generated in the schools_table, instead i want to create a drop down list and populate it with the school_name values taken from page one. but these drop down values should represent an int value behind the scene since it needs to go to school_id (department_table) but how can i convert the drop down values from string to int so that if i enter informatics from drop down the value will be 1 in the school_id column?
