如何从孤立的存储器中读取文本的各个行

本文关键字：读取 取文本 存储器 | 更新日期: 2023-09-27 18:01:26

如何在各自的文本块上读取每个单独输入的文本?当我激活阅读代码时，它们读取1个文本块中的2个文本。

保存代码:

private void OnSaveFile(string filePath)
    {
        StreamResourceInfo streamResourceInfo = Application.GetResourceStream(new Uri(filePath, UriKind.Relative));
        using (IsolatedStorageFile myIsolatedStorage = IsolatedStorageFile.GetUserStoreForApplication())
        {
            string directoryName = System.IO.Path.GetDirectoryName(filePath);
            if (!string.IsNullOrEmpty(directoryName) && !myIsolatedStorage.DirectoryExists(directoryName))
            {
                myIsolatedStorage.CreateDirectory(directoryName);
            }
            using (IsolatedStorageFileStream fileStream = myIsolatedStorage.OpenFile(filePath, FileMode.Create, FileAccess.Write))
            {
                using (StreamWriter writer = new StreamWriter(fileStream))
                {

                    writer.WriteLine(text1);
                    writer.WriteLine(text2);

                }
            }
        }
    }

阅读代码:

    private void OnReadSelected(string filePath)
        {
            using (IsolatedStorageFile myIsolatedStorage = IsolatedStorageFile.GetUserStoreForApplication())
            {
                if (myIsolatedStorage.FileExists(filePath))
                {
                    using (IsolatedStorageFileStream fileStream = myIsolatedStorage.OpenFile(filePath, FileMode.Open, FileAccess.Read))
                    {
                        using (StreamReader reader = new StreamReader(fileStream))
                        {
                            this.textBlocky1.Text = reader.ReadLine();
                            this.textBlocky2.Text = reader.ReadLine();
                        }
                    }
                }
                else
                {
                    MessageBox.Show("Files are not Found!");
                }
            }
        }

如何从孤立的存储器中读取文本的各个行

您将文本写成一行，然后将其读取为2。

代替:

string someTextData = textFileName.Text + text1.Text;    
writer.WriteLine(someTextData);

你可以这样做:

writer.WriteLine(textFileName.Text);   
writer.WriteLine(text1.Text);


下面是一个工作版本:

假设页面包含:

<TextBlock Text="item 1" />
<TextBox Name="textItem1" />
<TextBlock Text="item 2" />
<TextBox Name="textItem2" />
<Button Content="write" Click="WriteClick" />
<Button Content="read" Click="ReadClick" />

后面的代码可以满足你的要求。

private void WriteClick(object sender, RoutedEventArgs e)
{
    using (var store = IsolatedStorageFile.GetUserStoreForApplication())
    {
        using (var fileStream = store.OpenFile("myfile.txt", FileMode.Create, FileAccess.Write))
        {
            using (var writer = new StreamWriter(fileStream))
            {
                writer.WriteLine(textItem1.Text);
                writer.WriteLine(textItem2.Text);
            }
        }
    }
}
private void ReadClick(object sender, RoutedEventArgs e)
{
    using (var store = IsolatedStorageFile.GetUserStoreForApplication())
    {
        if (store.FileExists("myfile.txt"))
        {
            using (var fileStream = store.OpenFile("myfile.txt", FileMode.Open, FileAccess.Read))
            {
                using (var reader = new StreamReader(fileStream))
                {
                    textItem1.Text = reader.ReadLine();
                    textItem2.Text = reader.ReadLine();
                }
            }
        }
    }
}

在写u的时候，在你想作为单独的行读取的文本之间插入一个换行字符'n。Readline()函数读取，直到遇到换行字符，即'n。因此，无论您想将其作为单独的行读取，请在该行之后插入'n
