Try something like this:尝试这样的事情:
// read file content into a string
String fileContent = System.IO.File.ReadAllText(@"c:\file.dat");
// compare TextBox content with file content
if (fileContent.Equals(myTextBox.Text))
{
// do something

else

MessageBox.Show("Error!");

Take a look at StreamReader , that will allow you to read the file into your app.看看StreamReader ,它将允许您将文件读入您的应用程序。
