How Do Optional Parameters Solve API Integration Challenges in C#?

Optional parameters in C#

Prior to C# 4.0, the language did not support optional parameters, which created challenges when using procedurally generated web APIs. To overcome this limitation, let us consider the best approach.

The solution lies in the functionality of C# 4.0 and above, where optional parameters can be implemented seamlessly. This feature allows us to define parameters with default values, as shown in the following example:

<code class="language-c#">public void SomeMethod(int a, int b = 0)
{
   //一些代码
}</code>

In the above example, the SomeMethod method accepts two parameters, where the default value of b is 0. When calling this method, you can provide values ​​for both parameters, or you can choose to omit the value of b. This flexibility allows you to customize and simplify integration with API endpoints that accept query parameters.
