我编写了一个程序，可以从Crystal Report生成PDF文件，并将这些PDF文件发送电子邮件给某些人。 在我的开发机器上，该程序运行良好，但是当我将bin \ Release目录复制到Windows 2000 Server（我想要运行它的计算机）时，它开始运行，然后生成以下错误和堆栈跟踪信息：
The type initializer for 'CrystalDecisions.CrystalReports.Engine.ReportDocument' threw an exception.
at CrystalDecisions.CrystalReports.Engine.ReportDocument..ctor()
at DailyJobCostSummaryEmail.Program.crptToPDF(String reportFile, String jobNum, String outputLocation) in M:\Projects\DailyJobCostSummaryEmail\DailyJobCostSummaryEmail\Program.cs:line 79
at DailyJobCostSummaryEmail.Program.Main(String[] args) in M:\Projects\DailyJobCostSummaryEmail\DailyJobCostSummaryEmail\Program.cs:line 46
除了在Visual Studio中运行时，错误随处可见。
该机器上安装了.Net 2.0，并且我已经安装了CRRedist2005_x86.msi，但没有效果。即使我使用try / catch将异常打印到文件中，我甚至还会收到“发送错误报告给Microsoft”的对话框。即使catch块执行，我的程序也无法正确关闭。
static void Main(string[] args)
{
try
{
String dir = @"JobCostReports";
DataTable jobs = new DataTable();
using (SqlConnection conn = new SqlConnection(connString))
{
String sql = "JC_GetJobsClosedYesterday";
SqlDataAdapter da = new SqlDataAdapter(sql, conn);
da.Fill(jobs);
}
List<String> files = new List<String>();
foreach (DataRow row in jobs.Rows)
{
files.Add(crptToPDF(@"JobCost.rpt", row["JobNumber"].ToString().TrimEnd(), dir));
}
Utilities.sendEmail("[toEmail]",
"[FromEmail]",
"Job Cost Summaries for Yesterday",
"Attached are Job cost summaries for the " + files.Count + " jobs closed yesterday.",
files.ToArray());
Console.WriteLine("Email sent.");
}
catch (Exception e)
{
using (StreamWriter writer = new StreamWriter("errors.log", true))
{
writer.AutoFlush = true;
Console.WriteLine();
writer.WriteLine(e.Message);
writer.WriteLine(e.StackTrace);
}
Console.WriteLine(e.Message);
Console.WriteLine(e.StackTrace);
Console.Read();
}
finally { }
}
public static String crptToPDF(String reportFile, String jobNum, String outputLocation)
{
using (ReportDocument rpt = new ReportDocument())
{
rpt.Load(reportFile);
rpt.SetParameterValue("@vJobNumber", jobNum);
String output = outputLocation + @"\" + jobNum + "_JobCostSummary.pdf";
rpt.ExportToDisk(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat, output);
return output;
}
}
我是否没有包含所有必要的引用和使用语句？我尝试了很多组合，但没有效果。
