C# implements a small example of uploading photos to a physical path and saving the address to the database
C#实现上传照片到物理路径，并且将地址保存到数据库的小例子
效果：
思路：
首先，获取图片物理地址，然后进行判断将图片保存到文件夹下，再将图片的信息保存到数据库。
数据库：
create table image1 ( ID int identity(1,1) primary key, ImageName varchar(100) , ImageType varchar(20), ImagePath varchar(200) )
代码：
<body>
<form id="form1" runat="server">
<p>
<table>
<tr>
<td colspan="2" style="height: 21px">
</td>
</tr>
<tr>
<td style="width: 400px">
<asp:FileUpload ID="FileUpload1" runat="server" />
<asp:Label ID="label1" runat="server" ForeColor="Red"></asp:Label>
</td>
<td style="width: 80px">
<asp:Button ID="UploadButton" runat="server" Text="上传图片" OnClick="UploadButton_Click" />
</td>
</tr>
<tr>
<td colspan="2" align="center">
<br />
<br />
<asp:Image ID="Image1" runat="server" Height="118px" Width="131px" />
</td>
</tr>
</table>
</p>
</form>

using (SqlConnection sqlcon = new SqlConnection(SQLString))
{
string FullName = FileUpload1.PostedFile.FileName;//获取图片物理地址
FileInfo fi = new FileInfo(FullName);
string name = fi.Name;//获取图片名称
string type = fi.Extension;//获取图片类型
if (type == ".jpg" || type == ".gif" || type == ".bmp" || type == ".png")
{
string SavePath = Server.MapPath("~\\excel");//图片保存到文件夹下
this.FileUpload1.PostedFile.SaveAs(SavePath + "\\" + name);//保存路径
this.Image1.Visible = true;
this.Image1.ImageUrl = "~\\excel" + "\\" + name;//界面显示图片
string sql = "insert into image1(ImageName,ImageType,ImagePath) values('" + name + "','" + type + "','~\\excel" + name + "')";
SqlCommand cmd = new SqlCommand(sql, sqlcon);
sqlcon.Open();
cmd.ExecuteNonQuery();
this.label1.Text = "上传成功";

The difference between multithreading and asynchronous c#
Apr 03, 2025 pm 02:57 PM
The difference between multithreading and asynchronous is that multithreading executes multiple threads at the same time, while asynchronously performs operations without blocking the current thread. Multithreading is used for compute-intensive tasks, while asynchronously is used for user interaction. The advantage of multi-threading is to improve computing performance, while the advantage of asynchronous is to not block UI threads. Choosing multithreading or asynchronous depends on the nature of the task: Computation-intensive tasks use multithreading, tasks that interact with external resources and need to keep UI responsiveness use asynchronous.
MySQL: Simple Concepts for Easy Learning
Apr 10, 2025 am 09:29 AM
MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.
