C# Code Demonstration for Beginners (.NET Core Console Application)
Mobile apps, 2D and 3D games, web applications and more can be developed rapidly using C#. C# is a very powerful and flexible .NET programming language.
***NOTE***
In the example given, if the conversion from string to decimal (for the 'annualSalary' variable) causes a runtime error stating that the input string is not in the correct format, you can use the 'Decimal.Parse' method instead of the 'Convert.ToDecimal' method and pass the appropriate 'Console.ReadLine()' method as a parameter to the 'Decimal.Parse' method to resolve this.
Although the code provided in this tutorial is technically not incorrect (because the error is caused by an incompatible configuration setting) and many of you may not experience the issue it is safer to use the code provided below.
annualSalary = Decimal.Parse(Console.Readline(),
NumberStyles.AllowDecimalPoint, CultureInfo.InvariantCulture);
Include the following directive,
using System.Globalization;
under using System;
What causes this issue?
On some computers the settings may be such that when inputting a number containing a decimal point, certain culture related settings on the computer may prohibit the use of a full-stop within the inputted number (this is what causes the runtime error). A comma for e.g. may be accepted rather than the full-stop. To illuminate the issue altogether, please use the recommended code provided above.
