我是 linux ubuntu 和单声道运行时的新手，我尝试像通常在 windows 中那样连接到 oracle 11G （我在 windows 中尝试了 System.Data.OracleClient 和 Oracle.OracleClient 并且都运行良好） 但我在 ubuntu 中遇到了这个问题: System.DllNotFoundException: libclntsh.so 这是堆栈跟踪：
libclntsh.so
Description: HTTP 500. Error processing request.
Stack Trace:
System.DllNotFoundException: libclntsh.so

这是我到 oracle 的连接字符串，我使用了 System.data.oracleclient
string oradb = "Data Source=(DESCRIPTION="
+ "(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521)))"
+ "(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=orcl)));"
+ "User Id=hr;Password=hr;";
OracleConnection conn = new OracleConnection(oradb);
conn.Open();
OracleCommand command=new OracleCommand();
command.Connection=conn;
command.CommandText="select * from employee";
OracleDataReader reader=command.ExecuteReader();
while(reader.Read())
{
Response.Write(reader[0]+"<br>");
}
conn.Close();
command=null;
reader.Close();
reader=null;
