在Asp.net中运行外部可执行文件的内存限制

我在.NET 4.0中运行的C#Web应用程序中使用WkhtmltoPdf从 HTML文件生成PDF.通常一切正常,除非HTML文件的大小低于250KB.一旦HTML文件大小超过该值,运行wkhtmltopdf.exe的进程就会产生如下异常.在任务管理器上,我已经看到wkhtmltopdf.exe进程的内存值没有超过40,096 K的值,我相信这就是为什么在这两者之间放弃进程的原因.

我们如何配置外部exes的内存限制可以增加？有没有其他方法可以解决这个问题？

更多信息：
当我直接从命令行运行转换时,PDF生成正常.所以,它不太可能成为WkhtmlToPdf的问题.

错误来自localhost.我在DEV服务器上尝试过相同的结果.

Process object,the error says – {“Only part of a ReadProcessMemory or
WriteProcessMemory request was completed”},with the NativeErrorCode

我使用的代码：

var fileName = " - ";
    var wkhtmlDir = ConfigurationManager.AppSettings[Constants.AppSettings.ExportToPdfExecutablePath];
    var wkhtml = ConfigurationManager.AppSettings[Constants.AppSettings.ExportToPdfExecutablePath] + "wkhtmltopdf.exe";
    var p = new Process();


    string switches = "";
    switches += "--print-media-type ";
    switches += "--margin-top 10mm --margin-bottom 10mm --margin-right 5mm --margin-left 5mm ";
    switches += "--page-size A4 ";
    switches += "--disable-smart-shrinking ";

    var startInfo = new ProcessStartInfo
    {
        CreateNoWindow = true,FileName = wkhtml,Arguments = switches + " " + url + " " + fileName,UseShellExecute = false,RedirectStandardOutput = true,RedirectStandardError = true,RedirectStandardInput=true,WorkingDirectory=wkhtmlDir
    };

    p.StartInfo = startInfo;
    p.Start();

我找不到任何与“增加”进程的内存限制有关的内容,虽然我听说有人用MaxWorkingSet限制进程内存,但我相信这只适用于应用程序使用它之后的虚拟内存能够.

Job Object是一个很好的起点,它们只是一组易于控制的流程.

“With this library you can create job objects,create and assign a
process to the job,control process and job limits,and register for
the various process- and job-related notification events.”
