我需要帮助将4个文本框中的数据存储到数组中并将数据写入二进制文件。
将4个文本框中的数据存储到一个简单的数组中，然后添加一个保存按钮：
将4个文本框中的信息存储到数组
将4个文本框中的信息作为四个单独的项添加到二进制文件中 按书名
到目前为止，这是我的代码：
private void button1_Click(object sender, EventArgs e)
{
string[] strArray = new string[8];
int index1 = 0;
string text1 = this.txtAuthor.Text;
strArray[index1] = text1;
int index2 = 1;
string str1 = ", ";
strArray[index2] = str1;
int index3 = 2;
string text2 = this.txtDate.Text;
strArray[index3] = text2;
int index4 = 3;
string str2 = ". ";
strArray[index4] = str2;
int index5 = 4;
string text3 = this.txtTitle.Text;
strArray[index5] = text3;
int index6 = 5;
string str3 = ". ";
strArray[index6] = str3;
int index7 = 6;
string text4 = this.txtPublisher.Text;
strArray[index7] = text4;
int index8 = 7;
string str4 = ".";
strArray[index8] = str4;
this.txtOutput.Text = string.Concat(strArray);
}

我建议你以错误的方式解决这个问题。我对这个问题的理解是你想从你GUI中的4个输入创建你的“Book”类，这是Serializable。在这种情况下，我会修改你的书类，以包含一个带有4个参数的构造函数（标题，作者，出版商和日期）：
internal class Book
{
public Book(string title, string author, string publisher, string date)
{
Title = title;
Author = author;
Publisher = publisher;
Date = date;
}
public string Title { get; private set; }
public string Author { get; private set; }
public string Publisher { get; private set; }
public string Date { get; private set; }
public override string ToString()
{
return string.Format("{0}, {1}. {2}. {3}.", Author, Date, Title, Publisher);
}
}
然后你的button1_Click方法看起来像：
private void button1_Click(object sender, EventArgs e)
{
var title = this.txtTitle.Text;
// var author, date, publisher are similar
this.currentBook = new Book(title, author, publisher, date);
}
其中currentBook是Book。的类型成员变量。
最后，您的保存按钮方法现在看起来像：
private void btnSave_Click(object sender, EventArgs e)
{
var currentBookText = this.currentBook.ToString();
// write currentBookText to file.
}
您可以查看：https://msdn.microsoft.com/en-us/library/8bh11f1k.aspx，了解有关写入文件的信息。
然后，您可以轻松创建一个public static Book Book.FromString(string input)方法来反序列化您的图书文件。
C＃还可以为您处理序列化和反序列化。有关详细信息，请查看此处：https://msdn.microsoft.com/en-us/library/et91as27.aspx
