在C#中,writeline方法有以下几种用法:
Console.WriteLine("Hello World");
int num = 5;
Console.WriteLine(num);
string name = "John";
int age = 25;
Console.WriteLine("My name is {0} and I am {1} years old.", name, age);
string filePath = "example.txt";
string text = "Hello World";
System.IO.File.WriteAllText(filePath, text);
string filePath = "example.txt";
string text = "Hello World";
System.IO.File.AppendAllText(filePath, text);
这些是writeline方法的常见用法,但还有其他更多的用法可以根据具体需要进行使用。
