我找到了一种使用ReportExecutionService
Web 服务生成报告的方法。如果已将 Web 服务引用添加到项目中,这将生成具有给定参数的文件。此处开始和结束日期作为参数提供,并且使用Render() 方法生成报告。
private void GenerateReport()
{
ReportExecutionService rs = new ReportExecutionService();
rs.Credentials = System.Net.CredentialCache.DefaultCredentials;
rs.Url = "http://<TFS server name>/reportserver/ReportExecution2005.asmx";
// Render arguments
byte[] result = null;
string reportPath = @"<SSRS report path>";
string format = "PDF";
string historyID = null;
string devInfo = @"<DeviceInfo><Toolbar>False</Toolbar></DeviceInfo>";
// Prepare report parameter.
ParameterValue[] parameters = new ParameterValue[2];
parameters[0] = new ParameterValue();
parameters[0].Name = "StartDateParam";
parameters[0].Value = "2012-06-01 00:00:00";
parameters[1] = new ParameterValue();
parameters[1].Name = "EndDateParam";
parameters[1].Value = "2012-09-01 00:00:00";
parameters[2] = new ParameterValue();
parameters[2].Name = "AreaParam";
parameters[2].Value = "[Work Item].[Area Hierarchy].[All]";
parameters[3] = new ParameterValue();
parameters[3].Name = "WorkItemTypeParam";
parameters[3].Value = "[Work Item].[System_WorkItemType].&[Task]";
parameters[4] = new ParameterValue();
parameters[4].Name = "StateParam";
parameters[4].Value = "[Work Item].[System_State].&[Active]";
parameters[5] = new ParameterValue();
parameters[5].Name = "TrendLineParam";
parameters[5].Value = "both";
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);
var parameters_ = rs.GetExecutionInfo().Parameters;
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.pdf", 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);
}
}
顺便说一句,为参数设置的值是 MDX 查询,我还没有找到如何设置特定的 AreaPath,所以现在我只能列出“全部”。
