Is it possible to replace a substring in a string without assigning a return value?
I have a string:
string test = "Hello [REPLACE] world";
And I want to replace the substring [REPLACE]
with something else:
test = test.replace("[REPLACE]", "test");
This works fine, but how can I do it without assigning the return value to a variable?
I want something like this:
test.replace("[REPLACE]", "test");
C programming language is a machine-independent programming language that is mainly used to create many types of applications and operating systems such as Windows, and other complicated programs such as the Oracle database, Git, Python interpreter, and games and is considered a programming foundation in the process of ...
In the real sense it has no meaning or full form. It was developed by Dennis Ritchie and Ken Thompson at AT&T bell Lab. First, they used to call it as B language then later they made some improvement into it and renamed it as C and its superscript as C++ which was invented by Dr.
What is C? C is a general-purpose programming language created by Dennis Ritchie at the Bell Laboratories in 1972. It is a very popular language, despite being old. C is strongly associated with UNIX, as it was developed to write the UNIX operating system.
C is a general-purpose language that most programmers learn before moving on to more complex languages. From Unix and Windows to Tic Tac Toe and Photoshop, several of the most commonly used applications today have been built on C. It is easy to learn because: A simple syntax with only 32 keywords.
As mentioned by dlev, you can't do this with string
as strings are immutable in .NET - once a string has been constructed, there's nothing you can do (excluding unsafe code or reflection) to change the contents. This makes strings generally easier to work with, as you don't need to worry about defensive copying, they're naturally thread-safe etc.
Its mutable cousin, however, is StringBuilder
- which has a Replace
method to perform an in-object replacement. For example:
string x = "Hello [first] [second] world";
StringBuilder builder = new StringBuilder(x);
builder.Replace("[first]", "1st");
builder.Replace("[second]", "2nd");
string y = builder.ToString(); // Value of y is "Hello 1st 2nd world"
