启动项目报错

选择一下32位程序

发现还是不行，最后换成.net framework 4.8的控制台项目
添加dll的引用,dll需要去安装的wps里面查找

Console.WriteLine("转化开始");
var exePath = System.AppDomain.CurrentDomain.BaseDirectory;
var inputFile = Path.Combine(exePath, "001.docx");
var outputFile = Path.Combine(exePath, "001.pdf");
WordExportAsPdf(inputFile, outputFile);
Console.WriteLine("转化成功");
Console.ReadKey();

asp.net core也可以问题根本原因是路径的问题，不能些相对路径，必须绝对路径
