C#你能在一个变量中存储字符串格式吗？

string myString = "Hello, World!"; // 使用双引号定义字符串
string myString2 = @"C:\Program Files\"; // 使用@符号定义包含特殊字符的字符串

int age = 25;
string name = "John";
string message = $"My name is {name} and I'm {age} years old."; // 字符串插值
Console.WriteLine(message); // 输出：My name is John and I'm 25 years old.

string formattedString = string.Format("My name is {0} and I'm {1} years old.", name, age); // 字符串格式化
Console.WriteLine(formattedString); // 输出：My name is John and I'm 25 years old.

string str1 = "Hello";
string str2 = "World";
string concatenatedString = str1 + " " + str2; // 字符串拼接
Console.WriteLine(concatenatedString); // 输出：Hello World

string substring = concatenatedString.Substring(6, 5); // 字符串截取
Console.WriteLine(substring); // 输出：World

string replacedString = concatenatedString.Replace("World", "C#"); // 字符串替换
Console.WriteLine(replacedString); // 输出：Hello C#

int index = concatenatedString.IndexOf("World"); // 字符串查找
Console.WriteLine(index); // 输出：6
