对文件的简单操作

1.使用File对象操作文件:

private static void CreateSimpleFile() {

private static void CreateComplexFile() {

//创建文件,写入内容;

string fileName = ".\\complexFile.txt";

StreamWriter writer = new StreamWriter(fileName, false, System.Text.Encoding.GetEncoding("GB2312"));

writer.WriteLine("Hello StreamWriter!");

if (writer.Encoding == System.Text.Encoding.GetEncoding("GB2312"))

{

writer.WriteLine("swriter.Encoding is GB2312");

}

writer.Flush();

writer.Close();

//读入文件内容.

StreamReader reader = new StreamReader(fileName,System.Text.Encoding.GetEncoding("GB2312"),false,1024);

string line = reader.ReadLine();

Console.WriteLine(line);

line = reader.ReadLine();

Console.WriteLine(line);

reader.Close();

}
