String append. Strings can be appended one after another. There are no Append or Add methods on the string type. And strings must be copied, not modified in-place.
Notes, appending. We provide a quick reference for how to add one string on the end to an existing string. The concat operator can be used.
Example. Many programmers are familiar with appending strings, but the string type lacks an "Append" method. Instead, it is best to use the plus operator on different instances of strings.
Step 1 A string reference is assigned the literal value "cat." The word "and" is appended to the string with the "+=" operator.
Step 2 We append another word to the string. A new string is created, and the identifier "value" now points to it.
using System;
string value = "cat ";
// Step 1: append a word to the string.
value += "and ";
Console.WriteLine(value);
// Step 2: append another word.
value += "dog";
Console.WriteLine(value);cat and
cat and dog
Example 2. Let's look at how you can append string values—and append multiple values at once. This example creates a two-line string, using 3 string variables.
Also We see the Environment.NewLine property. This represents the newline sequence, which is 2 chars.
using System;
string value1 = "One";
string value2 = "Two";
// Append newline to string and also string.
value1 += Environment.NewLine + value2;
Console.WriteLine(value1);One
Two
Internals. When you compile one of the above C# programs, the compiler will transform the + operators into calls to String.Concat. You can use String.Concat for the same effect.
