【问题描述】：
我有一个网格视图，其中放置了一个链接按钮来打印报告。在此按钮单击事件中，我需要调用 SSRS 报告并需要将输出作为 PDF 文件。
我使用了下面的代码，代码运行良好，但我看不到打开/保存 pdf 文件的提示。
protected void btnAuthenticateAndPrint_Click(object sender, EventArgs args)
{
try
{
//Getting Values from grid
LinkButton lb = (LinkButton)sender;
GridViewRow row = (GridViewRow)lb.NamingContainer;
Label lbOrderID = row.FindControl("lbOrderID") as Label;
int OrderId = Convert.ToInt32(lbOrderID.Text);
da = new SqlDataAdapter("Get_PODetails", con);
da.SelectCommand.CommandType = CommandType.StoredProcedure;
da.SelectCommand.Parameters.AddWithValue("@MPDI_ID", OrderId);
ds = new DataSet();
da.Fill(ds, "PO");
if (ds.Tables["PO"].Rows.Count > 0)
{
lblPOId.Text=ds.Tables["PO"].Rows[0]["MPDI_ID"].ToString();
lblVendid.Text = ds.Tables["PO"].Rows[0]["MVDI_ID"].ToString();
lblBranch.Text = ds.Tables["PO"].Rows[0]["MBRI_ID"].ToString();
lblDate.Text = Convert.ToDateTime(ds.Tables["PO"].Rows[0]["MPDI_Date"]).ToString("dd-MM-yyyy");
}
//SSRS Report Print
rs = new RSWebService.ReportingService2005();
rsExec = new REWebService.ReportExecutionService();
rs.Credentials = System.Net.CredentialCache.DefaultCredentials;
rsExec.Credentials = System.Net.CredentialCache.DefaultCredentials;
rs.Url = "http://localhost/ReportServer/ReportService2005.asmx";
rsExec.Url = "http://localhost/ReportServer/ReportExecution2005.asmx";
byte[] Sendresults = null;
byte[] bytes = null;
string historyID = null;
string deviceInfo = @"<DeviceInfo><Toolbar>False</Toolbar></DeviceInfo>";
string format = "PDF";
string encoding = null;
string mimeType = null;
string extension = null;
REWebService.Warning[] warnings = null;
string[] streamIDs = null;
string _reportName = @"/FIMO GOF Assets Reports/PURCHASE ORDER";
REWebService.ExecutionInfo ei = rsExec.LoadReport(_reportName, historyID);
REWebService.ParameterValue[] parameters = new REWebService.ParameterValue[4];
parameters[0] = new REWebService.ParameterValue();
parameters[0].Name = "MVDI_ID";
parameters[0].Value = lblVendid.Text;
parameters[1] = new REWebService.ParameterValue();
parameters[1].Name = "MBRI_ID";
parameters[1].Value = lblBranch.Text;
parameters[2] = new REWebService.ParameterValue();
parameters[2].Name = "MPDI_Date";
parameters[2].Value = lblDate.Text;
parameters[3] = new REWebService.ParameterValue();
parameters[3].Name = "ReportParameter1";
parameters[3].Value = lblPOId.Text;
rsExec.SetExecutionParameters(parameters, "en-us");
Sendresults = rsExec.Render(format, deviceInfo, out extension, out encoding, out mimeType, out warnings, out streamIDs);
MemoryStream ms = new MemoryStream(Sendresults);
//To create a PDF
if (format == "PDF")
{
Response.ContentType = "application/pdf";
Response.AddHeader("Content-disposition", "inline;filename=output.pdf");
Response.AddHeader("Content-Length", Sendresults.Length.ToString());
}
Response.OutputStream.Write(Sendresults, 0, Sendresults.Length);
Response.OutputStream.Flush();
Response.OutputStream.Close();
}
catch(Exception Ex)
{
throw Ex;
}
}

我拼凑了一个看起来像这样的按钮单击-
protected void Button1_Click(object sender, EventArgs e) { Response.ContentType = "application/txt"; Response.AddHeader("Content-disposition", "inline;filename=output.pdf"); Response.AddHeader("Content-Length", "1"); Response.OutputStream.Write(new byte[] { 255 }, 0, 1); Response.OutputStream.Flush(); Response.OutputStream.Close(); } }当我单击时它给了我一个弹出窗口-您是否尝试设置断点以确保您的代码被调用？跨度> -
感谢您的回答，但是我们在哪里将 byte[] Sendresults 分配给此代码以刷新报告。我们是否还需要添加任何特定的命名空间/程序集..？

@vinay 我会尝试 chrispy 的评论，看看是否会为您弹出窗口。可能是您有另一个问题阻止弹出窗口，当您调整 chrisp 的代码以执行您想要的操作时会更加清晰。
