C#连接Oracle数据库

1、下载“Oracle.ManagedDataAccess.dll”；

2、在工程中添加引用“Oracle.ManagedDataAccess.dll”；

3、引用命名空间“using Oracle.ManagedDataAccess.Client;”

4、连接数据库代码如下：publi罕铞泱殳c bool Connect(string hostaddress, string servername, string uid, string pwd){ string connString = "Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST="+ hostaddress +")(PORT=1521))(CONNECT_DATA=(SERVICE_NAME="+ servername +")));Persist Security Info=True;User ID="+ uid +";Password="+ pwd +";"; OracleConnection conn = new OracleConnection(connString); conn.Open(); if(conn.State==ConnectionState.Open) { conn.Close(); return true; } else { return false; }}
