In the previous article, we discussed the basic data binding knowledge of the DataGrid. In today's tutorial, I will show you how to use the ADO. NET Entity Framework to perform basic interactions with databases. Overview To make things easier, I will first explain how to retrieve data from the database and return it to the DataGrid. This example shows the following functions: 1) Click the [get data] b

NET Framework | safety | security principal objects The principal object is an instance of the class that implements the IPrincipal interface, which represents the user and includes the user's identity information. The System.Security.Principal namespace includes several types of principal classes that encapsulate the security context in which program code runs. We'll see a sample code that checks the us

a given XML document. The function opens an XML document and then loops through all the contents of the XML document. Each time the Read method is called, the browser pointer moves down one node. In most cases, element nodes can be processed with the Read method, but sometimes when you move from one node to the next, you may move between two different types of nodes. However, the Read method cannot be moved between attribute nodes. The MoveToContent method of the browser allows the pointer to j

Through the previous article, I believe that you have a basic understanding of Quartz. Net and can establish the simplest service. This article describes how to set Trigger conditions for a service. According to the scenario, I usually encounter the following situations at work: 1. Execute when the service starts This Trigger has been used in the previous example. If you do not need to talk about it, directly add the code. ITrigger trigger = TriggerBu

For example, when large data is stored, dataprovider automatically enables the cache mechanism to improve data read efficiency. ● Isline.

attribute nodes in two ways. The first method is to use the Writestartatribute method to create a new attribute node to update the writer's state. The property value is then set using the WriteString method. After writing, use the WriteEndElement method to finish the node. In addition, you can also use the WriteAttributeString method to create a new attribute node, when the state of Writerr is element, writerattributestring start work, it creates a single attribute. Similarly, the WriteStartEle
