C# 复制与删除文件的实现方法
1、首先是复制文件
首先打开我们的对话框获得文件路径,当然也可以直接编写路径
private void BtnAddFile_Click(object sender, RoutedEventArgs e) { OpenFileDialog openFileDialog = new OpenFileDialog(); if (openFileDialog.ShowDialog() == System.Windows.Forms.DialogResult.OK) { string path = openFileDialog.FileName; // System.Windows.Forms.MessageBox.Show(path); MyFile.addFile(path); } }
然后是复制文件的方法买这里我写的是添加,是根据我的项目来的
MyFile是一个文件操作类,OpenFileDialog需要添加引用
public static void addFile(string path) { string[] s = path.Split('\\'); try { File.Copy(path, "E:\\Share\\"+s[s.Length-1], true); //path是你要复制的文件,第二个是目标路径,注意要获得文件名 } catch (Exception ex) { System.Windows.Forms.MessageBox.Show(ex.Message); } }
string[] s = path.Split("\\");这是一个分割字符串的方式,我们需要获得文件名,然后拼接成目标路径,我们是不能直接复制文件到文件夹中的
2、删除
public static void deleteFile(string path) { if (System.IO.File.Exists(path)) { try { System.IO.File.Delete(path); } catch (System.IO.IOException e) { Console.WriteLine(e.Message); return; } } }
The above is the detailed content of How to copy and delete files in C#. For more information, please follow other related articles on the PHP Chinese website!

C# and .NET runtime work closely together to empower developers to efficient, powerful and cross-platform development capabilities. 1) C# is a type-safe and object-oriented programming language designed to integrate seamlessly with the .NET framework. 2) The .NET runtime manages the execution of C# code, provides garbage collection, type safety and other services, and ensures efficient and cross-platform operation.

To start C#.NET development, you need to: 1. Understand the basic knowledge of C# and the core concepts of the .NET framework; 2. Master the basic concepts of variables, data types, control structures, functions and classes; 3. Learn advanced features of C#, such as LINQ and asynchronous programming; 4. Be familiar with debugging techniques and performance optimization methods for common errors. With these steps, you can gradually penetrate the world of C#.NET and write efficient applications.

The relationship between C# and .NET is inseparable, but they are not the same thing. C# is a programming language, while .NET is a development platform. C# is used to write code, compile into .NET's intermediate language (IL), and executed by the .NET runtime (CLR).

C#.NET is still important because it provides powerful tools and libraries that support multiple application development. 1) C# combines .NET framework to make development efficient and convenient. 2) C#'s type safety and garbage collection mechanism enhance its advantages. 3) .NET provides a cross-platform running environment and rich APIs, improving development flexibility.

C# and .NET adapt to the needs of emerging technologies through continuous updates and optimizations. 1) C# 9.0 and .NET5 introduce record type and performance optimization. 2) .NETCore enhances cloud native and containerized support. 3) ASP.NETCore integrates with modern web technologies. 4) ML.NET supports machine learning and artificial intelligence. 5) Asynchronous programming and best practices improve performance.

The programming process of C# in .NET includes the following steps: 1) writing C# code, 2) compiling into an intermediate language (IL), and 3) executing by the .NET runtime (CLR). The advantages of C# in .NET are its modern syntax, powerful type system and tight integration with the .NET framework, suitable for various development scenarios from desktop applications to web services.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
