Writing a json Easily and Elegently in in C# 11

 In the previous post "No More " Escaping Needed with C# 11" we have discussed, how the json can be writen in C# code, without having to escape each occurance of double quote, when we use the new C# 11 feature Raw String Literals. You might not want to hardcode the entire json in code, instead may want to use variables dynamically setting the json body content. Let's see how we can use String interpolation, in Raw String Leiterals to write json body elegently, and have variables dynamically set values in the josn.

No More " Escaping Needed with C# 11

Writing json body in C# code as a string variable value to pass on to a method or service, is something you may hate as you need to escape every " that you use in your json specification, even though you could use @ (verbatim string literals) to write multi-line strings.  With new Raw String Literals in c# 11, we can write " as content of the strings wihtout having to escape each instance. Let's explore bit about escaping double qutes with Raw String Literals.

string.Format & { }

C# developers often use string.Format in handling string. string.Format the { and } is used as a special character to identify the parameters.

For example:

scrollDepth = “10”

string.Format("DOWN {0}",scrollDepth)  generates a string DOWN 10.

But what if a { should be used as a value in the string. Is there a way to include { in the string?

To escape a { you can {{. So if you want to get the resultant string as “{DOWN 10}” the syntax to use is

string.Format("{{DOWN {0}}}",scrollDepth)
