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 添加到引用中，vb.Net 程序必须添加：

• oci.dll
• OraOps11w.dll
• oraociei11.dll
• msvcr71.dll

但我无法添加到参考中。实际上如何将这些文件添加到我的 vb.net 程序中？

Answer 1

您只需从以下网址下载 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

这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()
