The Java String join function is a method that allows you to concatenate multiple strings into a single string, using a specified delimiter. It takes an array or an iterable of strings as input, along with the delimiter that you want to use to separate the strings. The method then joins the strings together, inserting the delimiter between each string, and returns the resulting string. This function is useful when you need to combine multiple strings into a single string, such as when constructing a message or a file path. Keep reading below to learn how to Java String join in C#.

Java String join in C# With Example Code

Java developers who are transitioning to C# may find themselves looking for the equivalent of Java’s `String.join()` method. Fortunately, C# provides a similar method that works in much the same way.

The C# equivalent of `String.join()` is the `String.Join()` method. This method takes two arguments: a separator string and an array of strings to join together. The separator string is inserted between each string in the array.

Here’s an example of how to use `String.Join()` in C#:


string[] words = {"hello", "world", "!"};
string sentence = String.Join(" ", words);
Console.WriteLine(sentence);

In this example, we create an array of strings called `words` that contains three strings. We then use `String.Join()` to join these strings together with a space separator. The resulting string is stored in the `sentence` variable and printed to the console.

It’s worth noting that `String.Join()` is a static method of the `String` class, so you don’t need to create an instance of `String` to use it.

Overall, `String.Join()` is a useful method to have in your C# toolbox, especially if you’re used to working with Java’s `String.join()` method.

Equivalent of Java String join in C#

In conclusion, the equivalent Java String join function in C# is the String.Join method. This method allows developers to concatenate an array of strings into a single string, using a specified separator. It is a simple and efficient way to join strings in C#, and it offers a lot of flexibility in terms of the separator and the input array. Whether you are a Java developer transitioning to C# or a C# developer looking for a better way to join strings, the String.Join method is a powerful tool that can help you streamline your code and improve your productivity. So, if you haven’t already, give it a try and see how it can simplify your string manipulation tasks.
