ReportExecutionService怎么给多值参数赋值

我需要一个多值参数，类似于下图的代码，如果给ReportYear多值，该怎么处理呢？
这一段代码是从微软官网上粘贴过来的，
using System;
using System.IO;
using System.Web.Services.Protocols;
using myNamespace.MyReferenceName;

class Sample
{
static void Main(string[] args)
{
ReportExecutionService rs = new ReportExecutionService();
rs.Credentials = System.Net.CredentialCache.DefaultCredentials;
rs.Url = "http://myserver/reportserver/R ... 3B%3B

// Render arguments
byte[] result = null;
string reportPath = "/AdventureWorks Sample Reports/Employee Sales Summary";
string format = "MHTML";
string historyID = null;
string devInfo = @"<DeviceInfo><Toolbar>False</Toolbar></DeviceInfo>";

// Prepare report parameter.
ParameterValue[] parameters = new ParameterValue[3];
parameters[0] = new ParameterValue();
parameters[0].Name = "EmpID";
parameters[0].Value = "288";
parameters[1] = new ParameterValue();
parameters[1].Name = "ReportMonth";
parameters[1].Value = "6"; // June
parameters[2] = new ParameterValue();
parameters[2].Name = "ReportYear";
parameters[2].Value = "2004";

DataSourceCredentials[] credentials = null;
string showHideToggle = null;
string encoding;
string mimeType;
string extension;
Warning[] warnings = null;
ParameterValue[] reportHistoryParameters = null;
string[] streamIDs = null;

ExecutionInfo execInfo = new ExecutionInfo();
ExecutionHeader execHeader = new ExecutionHeader();

rs.ExecutionHeaderValue = execHeader;

execInfo = rs.LoadReport(reportPath, historyID);

rs.SetExecutionParameters(parameters, "en-us");
String SessionId = rs.ExecutionHeaderValue.ExecutionID;

Console.WriteLine("SessionID: {0}", rs.ExecutionHeaderValue.ExecutionID);


try
{
result = rs.Render(format, devInfo, out extension, out encoding, out mimeType, out warnings, out streamIDs);

execInfo = rs.GetExecutionInfo();

Console.WriteLine("Execution date and time: {0}", execInfo.ExecutionDateTime);


}
catch (SoapException e)
{
Console.WriteLine(e.Detail.OuterXml);
}
// Write the contents of the report to an MHTML file.
try
{
FileStream stream = File.Create("report.mht", result.Length);
Console.WriteLine("File created.");
stream.Write(result, 0, result.Length);
Console.WriteLine("Result written to the file.");
stream.Close();
}
catch (Exception e)
{
Console.WriteLine(e.Message);
}

}
}
