매개 변수

Report
The full path name of the report.

HistoryID
The ID of the report history snapshot. Set the ForRendering parameter to a value of true in order to retrieve parameter properties for a report history snapshot. Set the value to null (Nothing in Visual Basic) if you are retrieving parameters for a report that is not a report history snapshot.

ForRendering
A Boolean expression that indicates how the parameter values are to be used. If set to a value of true, parameter properties that are returned are based on the parameter data that was used during the execution of the report.

Values
The parameter values (ParameterValue objects) that can be validated against the parameters of a report that is managed by the report server.

Credentials
The data source credentials (DataSourceCredentials objects) that can be used to validate query parameters.

반환 값

An array of ReportParameter objects that lists the parameters for the report.

주의

If the execution setting for the report is Snapshot, the parameter metadata that is returned is the data that was used when the report history snapshot was created. If the execution setting for the report is Live, the parameter metadata returned represents the parameter data that is associated with the specified report.

If you provide a value for the HistoryID parameter and set the ForRendering parameter value to true, the parameter metadata returned represents the parameter data that was used when the report history snapshot was created. The value supplied for HistoryID is ignored if ForRendering is set to false.If ForRendering is false, the parameter metadata returned represents the parameter data that is currently associated with the specified report.

If any parameters values are based on a query and you are interested in returning the query-based parameters' valid values list, set ForRendering to true. In addition, for query-based parameters, you must pass in all of the credential information required to return the query parameters.

When using the GetReportParameters method to validate parameters, the ParameterValues parameter is required.

If report parameters do not exist for the given report, an empty ReportParameter array is returned.

예

To compile this code example, you must reference the Reporting Services WSDL and import certain namespaces. For more information, see 코드 예제 컴파일 및 실행. The following code example uses the GetReportParameters method to retrieve a list of parameter metadata for a report and then displays the name of each parameter:

Imports System
Imports System.Web.Services.Protocols

Class Sample
   Public Shared Sub Main()
      Dim rs As New ReportingService2005()
      rs.Credentials = System.Net.CredentialCache.DefaultCredentials

      Dim report As String = "/SampleReports/Employee Sales Summary"
      Dim forRendering As Boolean = False
      Dim historyID As String = Nothing
      Dim values As ParameterValue() = Nothing
      Dim credentials As DataSourceCredentials() = Nothing
      Dim parameters As ReportParameter() = Nothing

      Try
         parameters = rs.GetReportParameters(report, historyID, forRendering, values, credentials)

         If Not (parameters Is Nothing) Then
            Dim rp As ReportParameter
            For Each rp In parameters
               Console.WriteLine("Name: {0}", rp.Name)
            Next rp
         End If

      Catch e As SoapException
         Console.WriteLine(e.Detail.InnerXml.ToString())
      End Try
   End Sub 'Main
End Class 'Sample

using System;
using System.Web.Services.Protocols;

class Sample
{
   public static void Main()
   {
      ReportingService2005 rs = new ReportingService2005();
      rs.Credentials = System.Net.CredentialCache.DefaultCredentials;

      string report = "/SampleReports/Employee Sales Summary";
      bool forRendering = false;
      string historyID = null;
      ParameterValue[] values = null;
      DataSourceCredentials[] credentials = null;
      ReportParameter[] parameters = null;

      try
      {
         parameters = rs.GetReportParameters(report, historyID, forRendering, values, credentials);

         if (parameters != null)
         {
            foreach (ReportParameter rp in parameters)
            {
               Console.WriteLine("Name: {0}", rp.Name);
            }
         }
      }

      catch (SoapException e)
      {
         Console.WriteLine(e.Detail.InnerXml.ToString()); 
      }
   }
}
