我想在我的web應用程序中創建一個簡單的XtraReport。 爲此,我在App_Code文件夾中創建一個DataSet類,並從它的「服務器資源管理器」工具欄中拖動表格。但是這個新創建的DataSet類不會顯示在XtraReport的DataSource下拉列表中。此外,當我建立網站然後很多錯誤(幾乎16個消息+ 10個錯誤)發生象這些..如何在XtraReport中設置數據集
「錯誤:**
The type 'Oracle.DataAccess.Client.OracleCommand' exists in both 'c:\Windows\assembly\GAC_32\Oracle.DataAccess\2.112.3.0__89b483f429c47342\oracle.dataaccess.dll' and 'c:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.0\Oracle.DataAccess.dll' c:\Users\Awaidus\AppData\Local\Temp\Temporary ASP.NET Files\surveybuilder\8874cc1e\a1214053\App_Code.qqrotzbv.4.cs

等等等等等等等等等等。等等,等等等等等等等等等等等等
我所限定的在web.config中的ConnectionString文件是如下:
<connectionStrings>
<add name="OralceConnectionString"
connectionString="DATA SOURCE=SOHAIB;PASSWORD=pak;PERSIST SECURITY INFO=True;USER ID=AWAIDUS"
providerName="Oracle.DataAccess.Client" />
</connectionStrings>
,並從下面的「ConnectionManager.cs」此連接類如下:
public class ConnectionManager
{
public static OracleConnection getSohaibOracleConnection()
{
string connectionString = ConfigurationManager.ConnectionStrings["OralceConnectionString"].ConnectionString;
OracleConnection connection = new OracleConnection(connectionString);
connection.Open();
return connection;
}
}
它也提到在這裏,我創建App_Code文件夾以外的DataSet類(如網站或某處根文件夾else),那麼這些錯誤消失了,但DataSet類仍然不顯示在XtraReport頁面中。請幫助我。我很困擾這個問題。我做什麼用DataSet類創建XtraReport。 許多thanxx和問候,
