将oci.dll oracle客户端添加到vb.net

Question

我已经读过要连接到oracle，除了将oracle.dataaccess.dll添加到引用之外，vb.Net程序还要添加：

• OCI.DLL
• OraOps11w.dll
• oraociei11.dll
• MSVCR71.DLL

但我无法添加参考。如何将这些文件实际添加到我的vb.net程序中？

Answer 1

您只需从以下位置下载ODP.net： http://www.oracle.com/technetwork/topics/dotnet/downloads/index.html

然后添加对名为Oracle.ManagedDataAccess的项目的引用

以下是连接数据库并检索数据的示例代码：

Dim oradb As String = "Data Source=orcl;User Id=hr;Password=hr;"
Dim conn As New OracleConnection(oradb) 
conn.Open()
Dim cmd As New OracleCommand
cmd.Connection = conn
cmd.CommandText = "select department_name from departments where department_id = 10"
cmd.CommandType = CommandType.Text
Dim dr As OracleDataReader = cmd.ExecuteReader()
dr.Read()
Label1.Text = dr.Item("department_name")
conn.Dispose()
