Convert String to Date Time

[freeway]

I want to use the date part of Time[0] and add 21:00 to it for the time part in a Strategy to create a DateTime object.
I tried the following but got an error

Convert.ToDateTime.Time[0].ToString("MM/dd/yyyy" + " " + "21:00")

Convert.ToDateTime not valid in this context. CS0119.

How else can I accomplish this?

try
Time[0].AddHour(21).ToString("MM/dd/yyyy")

Get Compile Error CS1061 no definition for AddHour.

should be AddHours, missed the s

Thanks that is close to what I want to do but not quite it yet. By add 21:00 I mean I want to take the date part of Time[0] and have the time part be "21:00". I don't want to add 21 hours to what ever the time part of Time[0] is. So, if Time[0] is 08/01/2011 15:00 I want to end up with 08/01/2011 21:00.
In effect I just want to replace the time part of Tim[0] with 21:00.

Freeway,

I am happy to assist you.

Why not just get the day, month, and year, then create a new datetime object? For more information on methods associated with datetime objects, please see the following link.

Please let me know if I may assist further.

Here is the code I have now. I want to get the Daily ATR while processing on another time frame.
There is a Add(PeriodType.Day, 1); in the Initialze method

if (BarsInProgress == 1)
{
Print(Time[0] + " Index Date = " + Time[0].Date.AddHours(21).ToString("MM/dd/yyyy HH:mm:ss"));
Index = GetBar(Time[0].Date.AddHours(21));
dailyATR = ATR(BarsArray[1],10)[Index];
Print(Time[0] + " Index = " + Index.ToString() + " dailyATR = " + dailyATR.ToString());
}

The Index variable always has a value of 0. Can you help? I am in the Pacific Time zone. I noted that on the daily charts on my computer that the close time is 21:00. That is why I add 21 hours to the date.

OK I did note that the code should be Bars.GetBar.... But I don't think the values for dailyATR are correct yet.

TimeSpan tsTest = new TimeSpan(21, 00, 00);
DateTime dtResult = Time[0].Date.Add(tsTest);

I have the following code to calculate the daily ATR when on another time frame chart.
if (BarsInProgress == 1)
{
Index = Count - CurrentBars[1] - 2;
dailyATR = ATR(BarsArray[1],10)[Index];
}

When I compare the value calculated here to the values on a Daily chart they are not the same. Most of them are close but not =. Should they be the same?
