Escape them with backslashes.

"I want to learn \"C#\""

Use escape characters for example this code:

var message = "I want to learn \"c#\"";
Console.WriteLine(message);

will output:

I want to learn "c#"

As well as escaping quotes with backslashes, also see SO question 2911073 which explains how you could alternatively use double-quoting in a @-prefixed string:

string msg = @"I want to learn ""c#""";

string str = @"""Hi, "" I am programmer";

OUTPUT - "Hi, " I am programmer

I use:

var value = "'Field1','Field2','Field3'".Replace("'", "\"");

as opposed to the equivalent

var value = "\"Field1\",\"Field2\",\"Field3\"";

Because the former has far less noise than the latter, making it easier to see typo's etc.

I use it a lot in unit tests.

The Code:

string myString = "Hello " + ((char)34) + " World." + ((char)34);

Output will be:

Hello "World."

You can also declare a constant and use it each time. neat and avoids confusion:

const string myStrQuote = "\"";
