<\/p>\n

As a mid-level programmer, I always think about being more productive and optimized in my regular day jobs. C# and .NET are deep areas even for accomplished, experienced, developers. Though, I know right, I choose a nice clickbait title, but the tips I am gonna show you are not secretly stashed in the language.<\/p>\n

<\/p>\n

<\/p>\n

These are some techniques, I have summarized after reading so many countless basic articles & as per my experience. Each tip will be supported by sample code to make it more understandable for the C# newbies to get a hold on.<\/p>\n

\u00a0<\/p>\n

<\/p>\n

<\/p>\n

1. Conditional Operators:<\/h3>\n

<\/p>\n

<\/p>\n

The Conditional operator provides a fast and simple way of writing\u00a0if-else<\/em>\u00a0statements:<\/p>\n

<\/p>\n

<\/p>\n

\n

condition ? first_expression : second_expression;<\/em><\/code><\/p>\n<\/blockquote>\n

<\/p>\n

<\/p>\n

It means: If the\u00a0condition is true, return the first expression, else, return the second expression.
In this example, We have an\u00a0if else<\/code>\u00a0statement that demonstrates if the variable\u00a0number<\/code>\u00a0is greater than 5 and depending on the result, displays a particular message.<\/p>\n

<\/p>\n

<\/p>\n

\"\"<\/figure>\n

<\/p>\n

<\/p>\n

This code is fairly straightforward, but it could be written in far fewer lines and still be understandable:<\/p>\n

<\/p>\n

<\/p>\n

\"\"\n

\u00a0<\/p>\n

<\/figcaption>\n<\/figure>\n

<\/p>\n

<\/p>\n

\u00a0<\/h2>\n

2. Null coalescing operator:<\/h3>\n

<\/p>\n

<\/p>\n

The null coalescing operator returns left-hand operand if the operand isn’t null, and if it is, the right-hand operand is returned. Using\u00a0??<\/code>, we can avoid Null Reference Exception, which is thrown once we attempt to use something which is null.
Practically:<\/p>\n

<\/p>\n

<\/p>\n

\"\"<\/figure>\n

<\/p>\n

<\/p>\n

<\/p>\n

<\/p>\n

\u00a0<\/h3>\n

3. Null conditional Operator:<\/h3>\n

<\/p>\n

<\/p>\n

The\u00a0?<\/code>, null conditional operator, is a form of a member access operator. With a\u00a0null conditional operator<\/a>, the expression\u00a0class?.students<\/code>\u00a0evaluates to\u00a0students<\/code>\u00a0if the left operand,\u00a0class<\/code>, is non-null; otherwise, it evaluates to null.<\/p>\n

<\/p>\n

<\/p>\n

This example shows how to check if\u00a0book<\/code>\u00a0has chapters by using a\u00a0null conditional<\/em>\u00a0operator, so we don\u2019t need to check for nulability of this property.<\/p>\n

<\/p>\n

<\/p>\n

\"\"<\/figure>\n

<\/p>\n

<\/p>\n

If the\u00a0book<\/code>\u00a0doesn\u2019t have\u00a0Chapters<\/code>, the\u00a0numberOfChapters<\/code>\u00a0will equals 0.<\/p>\n

<\/p>\n

<\/p>\n

<\/p>\n

<\/p>\n

\u00a0<\/h3>\n

4. String Builder:<\/h3>\n

<\/p>\n

<\/p>\n

If you have a situation where you need to append many strings \u2014 especially if they are large \u2014 use\u00a0StringBuilder<\/em>\u00a0instead of\u00a0String<\/em>.\u00a0String<\/em>\u00a0is an immutable type which suggests that whenever you modify its value, you create a\u00a0replacement String<\/em>\u00a0or\u00a0new String<\/em>\u00a0object. Because of that, your application can become very slow once you got to perform this operation repeatedly.<\/p>\n

<\/p>\n

<\/p>\n

\"\"<\/figure>\n

<\/p>\n

<\/p>\n

\n
\"\"<\/figure>\n<\/div>\n

<\/p>\n

<\/p>\n

\u00a0<\/h3>\n

5. Avoid race condition with TryGetValue method:<\/h3>\n

<\/p>\n

<\/p>\n

It\u2019s a good idea, to try to write the right safe code wherever possible in your C# application. There are multiple ways of doing that in C# and in .NET.
Take a look at the below image and comments before each line.<\/p>\n

<\/p>\n

<\/p>\n

\"\"<\/figure>\n

<\/p>\n

<\/p>\n

The difference is I\u2019ve cached the copy of the value here in this result variable in line#14. So even if the dictionary item gets removed by the time we get to line#16, I\u2019ve got the cached copy here in this result variable.<\/p>\n

<\/p>\n

<\/p>\n

So, the tip is, use try-get-value, to write the right safe-code and if statements.<\/p>\n

<\/p>\n

<\/p>\n

These are five straightforward suggestions for making coding easier and more understandable.
