我在写文件的时候用Line 26: {
Line 27: StreamWriter sw = File.AppendText("Text.txt");
Line 28: sw.WriteLine("hello");
Line 29: sw.Flush();
Line 30: sw.Close();提示sw.WriteLine("hello"); CS1519: Invalid token '(' in class, struct, or interface member declaration请问哪里错了
Line 27: StreamWriter sw = File.AppendText("Text.txt");
Line 28: sw.WriteLine("hello");
Line 29: sw.Flush();
Line 30: sw.Close();提示sw.WriteLine("hello"); CS1519: Invalid token '(' in class, struct, or interface member declaration请问哪里错了
sw.Flush();
sw.Close();
放到方法快中
using System.IO;class Test
{
public static void Main()
{
string path = @"c:\temp\MyTest.txt";
// This text is added only once to the file.
if (!File.Exists(path))
{
// Create a file to write to.
using (StreamWriter sw = File.CreateText(path))
{
sw.WriteLine("Hello");
sw.WriteLine("And");
sw.WriteLine("Welcome");
}
} // This text is always added, making the file longer over time
// if it is not deleted.
using (StreamWriter sw = File.AppendText(path))
{
sw.WriteLine("This");
sw.WriteLine("is Extra");
sw.WriteLine("Text");
} // Open the file to read from.
using (StreamReader sr = File.OpenText(path))
{
string s = "";
while ((s = sr.ReadLine()) != null)
{
Console.WriteLine(s);
}
}
}
}老虎传送门
using(StreamWriter sw = File.AppendText("Text.txt"))
