The lastIndexOf() function in JavaScript is a method that is used to search for a specified string within a given string and returns the index of the last occurrence of the specified string. It takes in a string as an argument and searches for the last occurrence of that string within the given string. If the specified string is found, the function returns the index of the last occurrence of the string. If the specified string is not found, the function returns -1. The lastIndexOf() function is useful when you need to find the position of the last occurrence of a specific character or substring within a string.

Javascript String lastIndexOf in C# With Example Code
JavaScript’s `lastIndexOf()` method is a useful tool for finding the last occurrence of a specified character or substring within a string. While C# does not have a built-in `lastIndexOf()` method for strings, it is possible to replicate this functionality using the `LastIndexOf()` method.
To use `LastIndexOf()` in C#, simply call the method on a string object and pass in the character or substring you want to search for as an argument. The method will return the index of the last occurrence of the specified character or substring within the string, or -1 if it is not found.
Here is an example of using `LastIndexOf()` in C# to find the last occurrence of the letter “o” in a string:
string myString = "Hello World";
int lastIndex = myString.LastIndexOf("o");
Console.WriteLine(lastIndex); // Output: 7
In this example, the `LastIndexOf()` method is called on the `myString` object with the argument “o”. The method returns the index of the last occurrence of “o” within the string, which is 7. This value is then printed to the console using the `Console.WriteLine()` method.
By using the `LastIndexOf()` method in C#, you can easily find the last occurrence of a character or substring within a string, just like you would with JavaScript’s `lastIndexOf()` method.
Equivalent of Javascript String lastIndexOf in C#
In conclusion, the C# programming language provides a powerful and efficient equivalent to the Javascript String lastIndexOf function. The LastIndexOf method in C# allows developers to search for the last occurrence of a specified character or substring within a given string. This method is highly useful in a variety of programming scenarios, such as parsing text data or manipulating strings in complex algorithms. By leveraging the LastIndexOf method in C#, developers can write more efficient and effective code, ultimately leading to better software performance and user experience. Overall, the LastIndexOf method in C# is a valuable tool for any developer working with string manipulation in their code.
