How to fetch the contents of the path from the database

protected void page_load(object sender, eventargs e)

Get the file path.

string strfilename = "F: 3c group doc txt");

Instantiate a file class.

streamreader strreader = new streamreader(strfilename);

Read all the contents of the file.

Close the file (required).

Addendum: That's true, after testing, you can only use relative paths, not absolute paths, for what you said about how to separate that txt file from the whole path, I think this should be very simple, you can't write the file to the database is to write the absolute path, right? The key lies in the path you write the data, if you don't understand, send me a short message to discuss together, and it's best to add your QQ number.

Read with a stream! It is then printed onto the page.

1. Double-click to open the link to open the corresponding total connection.

2. Double-click the database to open the database and activate the corresponding content.

3. You can see the specific content under the database, such as **, etc.

4. Click on the table to view the specific data**, different**.

5. Double-click the data on the left to open the specific.

6. You can display all the specific content and detailed information in the table.

This required hyperlink points to the absolute path of the file on the server, i.e. the compilation path of the file obtained below

**Get the compilation path of the current project.

For example, e: MyEclipse Workspace MyProject Build Classes

/string filepath = "").getpath();

Get the compilation path where the upload file is located in the current project.

For example, e: MyEclipse Workspace MyProject Build Classes Upload

/string filepath ="upload/").getpath();

string extend =

lastindexof("."));

The extension of the file.

string folder = "/" + "/" + "/" + "/";

The directory where the uploaded file is stored.

folder);

create a folder, getbase(request); Get the physical path (location in disk) of the item

string imgpath = folder + extend;The relative path (without the drive letter) that produces a new **

getbase(request) +imgpath);Upload the file (here it's just copied because the upload thing has already been done before).

This path is inserted into the database.

worker = ;

Insert a record into the database.

When querying, you can get the path to insert into the database.

You're talking about an Internet café, first of all, you need to open the database port of the router where the server is located, such as 1433 for SQL Server and 3306 for MySQL, the database client software is used to connect (with IP address) + port number. You also need an account password, etc.

For example, use SQL Server's query analyzer), or you can use remote desktop to connect directly to the server and directly manipulate anything on the server), specific settings for the server to allow remote desktop connection, router port configuration.

Copy the database path and enter it on the command line.

Connect directly, then turn on.

JSP is displayed by loading the path, which can be saved in the project or saved to a certain road on disk. **Put it under webroot, generally it is webroot to create an img or pic folder to save pictures. jsp is used so that it can be loaded to **.

So why not just save the content of the text?

Just put the taken value in.

Read out the path to the database, and then construct the address string as the address of image src.

You don't specify what the database system is, and you don't specify what format the export file is, according to the analysis of the export file name you provide, it is estimated that it is the generated SQL scripts (SQL script), if you export this script contains the entire database structure definition and data, then you can't directly take out one of the table definitions and data. But SQL scripts can be used directly with a simple texter or a tool for writing **, and you can use the following methods to generate a script that only you need to extract the table definition and data:

1) Open the file with the user, use the search function of the device (generally CTL+F), find the string of the table name you need, after finding it, keep the structure definition and data items of the table you need, and delete the definition and data of the table that you need up and down. Save as another file. (You can also copy part of the definition and data part of the found table to a new file and save it, how to do it depends on the size of the script and your familiarity with SQL scripts).

2) Use this new script to execute and import the tables you need.

Of course, if you need to automate the import and export in the program, and the export content is not controlled by your program, then the above method is not suitable, you can only import all the exported content into a temporary library, and then copy the tables you need in the temporary library to the actual database you use.

Extract the SQL statements in it and rebuild a SQL document
