与 OLE DB 或 ADO 不同,如果“Persist Security Info ”值设置为false(默认值),则返回的连接字符串与用户设置的ConnectionString相同但去除了安全信息。除非将“Persist Security Info ”设置为true,否则,SQL Server.NET Framework 数据提供程序将不会保持,也不会返回连接字符串中的密码。 可以使用ConnectionString属性...
SqlConnectionStringBuilder connStr = new SqlConnectionStringBuilder(); connStr.DataSource = "192.168.1.20"; connStr.InitialCatalog = "rzerp_zjsy"; connStr.UserID = "developer"; connStr.Password = "developer"; //创建连接对象1 using (SqlConnection conn1 = new SqlConnection(connStr.ConnectionSt...
cnn.dispose（） 释放con对象所占用的资源，释放后这个对象就不可用了，所以出现“ConnectionString 属性...
在sqlserver中,我们可以使用 SqlBulkCopy 进行大数据量的插入。 2. 简单示例 先看个示例: var connString = "Data Source=192.168.252.129;Initial Catalog=test;User ID=sa;Password=123456;Encrypt=True; TrustServerCertificate=True;"; var conn = new SqlConnection(connString); conn.Open(); var cmd = ...
默认的,Entity Framework的看起来命名为为对象上下文类(如本项目MovieDBContext)的相同的一个连接字符串。有关详细信息,请参见SQL Server Connection Strings for ASP.NET Web Applications。 打开应用程序根目录的Web.config文件。(不是View文件夹下的Web.config文件。)打开红色高亮标记的Web.config文件。

简介:利用vs2019自带的sql server创建数据库并用c#连接 最近在做一个数据库的综合性实验,我之前用的都是Oracle的SQL developer来设计数据库,所以想尝试一下用SQL server进行设计,不得不说SQL用起来更方便,创建表格直接填写id和数据段类型就可以了。好了,说正经事,教程开始。
