Combining Separate Date and Time Strings in C# to Create a DateTime Object
When working with data, especially from sources like CSV files, it's common to come across date and time stored in different fields. If you find yourself with separate date and time strings that need to be combined into a DateTime object in C# , you've come to the right place.
In this guide, we’ll address a common problem: how to combine separate strings for date and time effectively without sacrificing performance in your C# applications.
The Problem
You may find yourself dealing with a CSV table structured like this:
objectIDTimeNameDate007:22 AMBonbon2022-03-14103:15 PMPie2022-03-23Your goal is to merge the date and time into a DateTime object for further processing. A naive string concatenation approach could look something like this:

However, you aim to minimize string conversions, especially in a loop, as performance can degrade with multiple conversions.
Solutions
Method 1: String Concatenation
The most straightforward method involves concatenating the date and time strings into one string and then parsing it.

Advantages:
Simplicity: Requires only basic string manipulations.
Parsing Once: You parse the combined string just a single time.
Method 2: Constructing a DateTime via TimeSpan
If you prefer the approach of combining two DateTime objects rather than using strings, you can work with a TimeSpan. Here’s how:
Parse the date.
Parse the time of the current day.
Subtract DateTime.Today from the time to get a TimeSpan.
Add this TimeSpan to the parsed date.
This can be executed as follows:

Advantages:
No String Manipulations: Operates entirely with DateTime objects.
Can be Useful for Time Comparisons: Allows for more granular control when handling time calculations.
Performance Considerations
Both methods demonstrated are efficient; the difference in performance is minimal. Generally, the first method using string concatenation is slightly faster since it entails parsing only once. If performance is critical:
Use the first method when dealing with straightforward conversions.
Use the second method if you find it more intuitive, or need to perform adjustments or calculations with the time.
Conclusion
Combining separate date and time strings in C# can be done efficiently with one of the two methods described above. Your choice should depend on your specific situation and coding preferences. Both techniques will allow you to work effectively with date and time data in your applications.
Feel free to experiment with both methods, and choose the one that best fits your coding style and the needs of your project. Happy coding!
