使用以下代码
写入文本文件时遇到实际问题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();
};
}
当双击完成时,它应该将文本块的内容保存到文件中,但我有三个错误
'System.IO.StreamWriter.StreamWriter(System.IO.Stream)'的最佳重载方法匹配有一些无效的参数(这是在Streamwriter线上)
无法从'string'转换为'System.IO.Stream'(在同一行)
'System.IO.StreamWriter'不包含'Close'的定义,并且没有可以找到接受类型'System.IO.StreamWriter'的第一个参数的扩展方法'Close'(你是否缺少using指令或汇编参考?)(这是关闭线)
如您所见,我有SYstem.io参考
任何我出错的想法?
任何帮助表示赞赏

使用File.WriteAllText。它是一种静态方法,与打开,写入和关闭文件的方法相同。请记住,代码越少,错误越少。
if (p2 > 210 && p2 < 235 && p1 > 339 && p1 < 367)
{
string dave = Environment.NewLine + Text3.Text + "," + Text4.Text;
File.WriteAllText(@"C:\myfile.txt", dave);
}
