Question

我正在尝试使用wkhtmltopdf将链接（例如www.google.com）转换为PDF（请参阅Calling wkhtmltopdf to generate PDF from HTML）但在此我收到的错误是pdf未生成但代码运行正常且返回0作为回复。

代码：

public static bool HtmlToPdf(string Url, string outputFilename)
{
    // assemble destination PDF file name
    string filename = @"C:\Users\Documents\visual studio 2012\Projects\PenchKin\PenchKin\Setup\test.pdf";

    // get proj no for header
    //Project project = new Project(int.Parse(outputFilename));

    var p = new System.Diagnostics.Process();
    p.StartInfo.FileName = @"C:\Users\documents\visual studio 2012\Projects\PenchKin\PenchKin\Setup\wkhtmltopdf-0.9.9-installer.exe";

    string switches = "--print-media-type ";
    switches += "--margin-top 4mm --margin-bottom 4mm --margin-right 0mm --margin-left 0mm ";
    switches += "--page-size A4 ";
    switches += "--no-background ";
    switches += "--redirect-delay 100";

    p.StartInfo.Arguments = switches + " " + Url + " " + filename;
    p.StartInfo.UseShellExecute = false; // needs to be false in order to redirect output
    p.StartInfo.RedirectStandardOutput = true;
    p.StartInfo.RedirectStandardError = true;
    p.StartInfo.RedirectStandardInput = true; // redirect all 3, as it should be all 3 or none
    p.StartInfo.WorkingDirectory = p.StartInfo.FileName;

    p.Start();

    // read the output here...
    string output = p.StandardOutput.ReadToEnd();

    // ...then wait n milliseconds for exit (as after exit, it can't read the output)
    p.WaitForExit(60000);

    // read the exit code, close process
    int returnCode = p.ExitCode;
    p.Close();

    // if 0 or 2, it worked (not sure about other values, I want a better way to confirm this)
    return (returnCode == 0 || returnCode == 2);
}

请帮我解决这个问题。

您应该指向实际的exe，而不是安装程序。替换

p.StartInfo.FileName = @"C:\Users\documents\visual studio 2012\Projects\PenchKin\PenchKin\Setup\wkhtmltopdf-0.9.9-installer.exe";

通过

p.StartInfo.FileName = @"C:\path\to\binary\wkhtmltopdf.exe";

无法使用wkhtmltopdf从HTML生成PDF
