[英]Writing to and reading from a text file - C# Windows Universal Platform App Windows 10
[英]c# windows app writing text to file
使用以下代碼在寫入文本文件時遇到實際問題
using HCP1.Common;
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using Windows.UI.Xaml.Media.Imaging;
using System.Runtime.InteropServices.WindowsRuntime;
using Windows.Foundation;
using Windows.Foundation.Collections;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls;
using Windows.UI.Xaml.Controls.Primitives;
using Windows.UI.Xaml.Data;
using Windows.UI.Xaml.Input;
using Windows.UI.Xaml.Media;
using Windows.UI.Xaml.Navigation;
using Windows.Storage;
using System.Threading.Tasks;
using System.Text;
using System.Diagnostics;
private void imageview_DoubleTapped(object sender, DoubleTappedRoutedEventArgs e)
{
var point = e.GetPosition(imageview);
var p1 = (int)point.X;
var p2 = (int)point.Y;
string stringVal1;
string stringVal2;
stringVal1 = System.Convert.ToString(p1);
stringVal2 = System.Convert.ToString(p2);
Text3.Text = stringVal1;
Text4.Text = stringVal2;
if (p2 > 210 && p2 < 235 && p1 > 339 && p1 < 367) {
string dave = Environment.NewLine + Text3.Text + "," + Text4.Text;
string path = @"C:\myfile.txt";
StreamWriter sw = new StreamWriter(path);
string bufferOne = dave;
sw.Write(bufferOne);
sw.Close();
sw.Dispose();
};
}
雙擊完成后,應將文本塊的內容保存到文件中,但出現三個錯誤
最佳重載方法匹配'System.IO.StreamWriter.StreamWriter(System.IO.Stream)'有一些無效的參數(這在Streamwriter行)
無法從“字符串”轉換為“ System.IO.Stream”(在同一行)
'System.IO.StreamWriter'不包含'Close'的定義,並且找不到擴展方法'Close'接受類型為'System.IO.StreamWriter'的第一個參數(您是否缺少using指令或程序集引用?)(在結束行)
如您所見,我有SYstem.io參考
任何想法,我錯了嗎?
任何幫助表示贊賞
標記
使用File.WriteAllText 。 這是一個靜態方法,與打開,寫入和關閉文件相同。 請記住,代碼越少,錯誤越少。
if (p2 > 210 && p2 < 235 && p1 > 339 && p1 < 367)
{
string dave = Environment.NewLine + Text3.Text + "," + Text4.Text;
File.WriteAllText(@"C:\myfile.txt", dave);
}
