C# 链接Sql和Access数据库语句

1、sql数据库：

1.1、链接数据语句：server=localhost;database=Data; uid=sa;pwd=123; 或

Data Source=localhost;DataBase=Data;Uid=sa;Pwd=123;

1.2、代码链接数据库：

           SqlConnectionStringBuilder csbuilder = new SqlConnectionStringBuilder();

            csbuilder.DataSource = "localhost";//Sql链接实例

            csbuilder.InitialCatalog = "Data";//数据库名称

            csbuilder.UserID = "sa";//链接数据的用户ID

            csbuilder.Password = "123";//用户密码

2、Access链接数：

      1.1、链接数据语句：

Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|News.mdb

      1.2、代码链接数据库：

             OleDbConnectionStringBuilder oleString = new OleDbConnectionStringBuilder();

              oleString.Provider = "Microsoft.Jet.OLEDB.4.0";

              oleString.DataSource = "News.mdb";
