使用wkhtmltopdf第三方包将HTML转为PDF的程序
1、这里使用的wkhtmltopdf.exe第三方包辅助（下载方式贴到最下方）2、废话不多少直接上代码（直接运行，帖主亲自试过）
public static bool HtmlConvertToPdf(string htmlPath, string savePath)
{
bool flag = false;
CheckFilePath(savePath);
///这个路径为程序集的目录，因为我把应用程序 wkhtmltopdf.exe 放在了程序集同一个目录下
string exePath = AppDomain.CurrentDomain.BaseDirectory.ToString() + "wkhtmltopdf.exe";
if (!File.Exists(exePath))
{
throw new Exception("No application wkhtmltopdf.exe was found.");
}
try
{
ProcessStartInfo processStartInfo = new ProcessStartInfo();
processStartInfo.FileName = exePath;
processStartInfo.WorkingDirectory = Path.GetDirectoryName(exePath);
processStartInfo.UseShellExecute = false;
processStartInfo.CreateNoWindow = true;
processStartInfo.RedirectStandardInput = true;
processStartInfo.RedirectStandardOutput = true;
processStartInfo.RedirectStandardError = true;
processStartInfo.Arguments = GetArguments(htmlPath, savePath);
Process process = new Process();
process.StartInfo = processStartInfo;
process.Start();
process.WaitForExit(60000);
///用于查看是否返回错误信息
StreamReader srone = process.StandardError;
StreamReader srtwo = process.StandardOutput;
string ss1 = srone.ReadToEnd();
string ss2 = srtwo.ReadToEnd();
srone.Close();
srone.Dispose();
srtwo.Close();
srtwo.Dispose();
process.Close();
process.Dispose();
flag = true;
}
catch
{
flag = false;
}
return flag;
}
private static void CheckFilePath(string savePath)
{
string ext = string.Empty;
string path = string.Empty;
string fileName = string.Empty;
ext = Path.GetExtension(savePath);
if (string.IsNullOrEmpty(ext) || ext.ToLower() != ".pdf")
{
throw new Exception("Extension error:This method is used to generate PDF files.");
}
fileName = Path.GetFileName(savePath);
if (string.IsNullOrEmpty(fileName))
{
throw new Exception("File name is empty.");
}
try
{
path = savePath.Substring(0, savePath.IndexOf(fileName));
if (!Directory.Exists(path))
{
Directory.CreateDirectory(path);
}
}
catch
{
throw new Exception("The file path does not exist.");
}
}
private static void CheckFilePath(string savePath)
{
string ext = string.Empty;
string path = string.Empty;
string fileName = string.Empty;
ext = Path.GetExtension(savePath);
if (string.IsNullOrEmpty(ext) || ext.ToLower() != ".pdf")
{
throw new Exception("Extension error:This method is used to generate PDF files.");
}
fileName = Path.GetFileName(savePath);
if (string.IsNullOrEmpty(fileName))
{
throw new Exception("File name is empty.");
}
try
{
path = savePath.Substring(0, savePath.IndexOf(fileName));
if (!Directory.Exists(path))
{
Directory.CreateDirectory(path);
}
}
catch
{
throw new Exception("The file path does not exist.");
}
}
// 在main函数直接调用HtmlConvertToPdf(htmlPath, savePath);

两个 CheckFilePath 函数？
复制多了一个，替换成我下方的
private static string GetArguments(string htmlPath, string savePath)
{
if (string.IsNullOrEmpty(htmlPath))
{
throw new Exception("HTML local path or network address can not be empty.");
}
if (string.IsNullOrEmpty(savePath))
{
throw new Exception("The path saved by the PDF document can not be empty.");
}
StringBuilder stringBuilder = new StringBuilder();
stringBuilder.Append(" --page-height 100 "); //页面高度100mm
stringBuilder.Append(" --page-width 100 "); //页面宽度100mm
stringBuilder.Append(" --header-center 我是页眉 ");//设置居中显示页眉
stringBuilder.Append(" --header-line "); //页眉和内容之间显示一条直线
stringBuilder.Append(" --footer-center \"Pageof \" "); //设置居中显示页脚
stringBuilder.Append(" --footer-line "); //页脚和内容之间显示一条直线
stringBuilder.Append(" " + htmlPath + " "); //本地 HTML 的文件路径或网页 HTML 的URL地址
stringBuilder.Append(" " + savePath + " "); //生成的 PDF 文档的保存路径
return stringBuilder.ToString();

Good!{:301_978:} 支不支持Ajax的网页 yunruifuzhu 发表于 2021-12-22 17:35
支不支持Ajax的网页
应该可以的 两个 CheckFilePath 函数？ 不错哦，很棒 迷恋自留地 发表于 2021-12-23 10:53
不错哦，很棒
谢谢支持 效果图呢，能保存连续不分页的吗 ygx0769 发表于 2021-12-24 22:41
效果图呢，能保存连续不分页的吗
