使用LINQ to Entities(EF)和Oracle 12.1忽略搜索时的重音符号

我用过甲骨文 NLS session parameters 解决我的问题。

 if(condition == true)
   AlterSortSession(context);

 public void AlterSortSession(MyContext context)
 {
   var connection = (OracleConnection)context.Database.Connection;
   connection.StateChange += AlterSortSession;
 }

 private static void AlterSortSession(object sender, StateChangeEventArgs e)
 {
  if (e.CurrentState != ConnectionState.Open)
    return;

  var connection = (OracleConnection)sender;
  OracleGlobalization info = connection.GetSessionInfo();

  info.Sort = "XGERMAN_DIN_AI";
  info.Comparison = "LINGUISTIC";

  connection.SetSessionInfo(info);
}

文件可用 here 对于 OracleGlobalization
