C# TextWriter 类是一个抽象类。它用于将文本或连续的一系列字符写入文件。它位于 System.IO 命名空间中。
让我们看一下 TextWriter 类写入两行数据的简单示例。
using System;
using System.IO;
namespace TextWriterExample
{
class Program
{
static void Main(string[] args)
{
using (TextWriter writer = File.CreateText("e:\\f.txt"))
{
writer.WriteLine("Hello C#");
writer.WriteLine("C# File Handling by RocSchool");
}
Console.WriteLine("Data written successfully...");
}
}
}
输出:
Data written successfully...
f.txt:
Hello C# C# File Handling by RocSchool
