C#调用JS C#调用JS的几种方法

phantomjs XX.js 参数1 参数2

//注意：保证phantomjs.exe和js在生成目录下存在
string url = "传参";
//这里调用cmd.exe
Process pProcess = new Process();
//调用phantomjs.exe
pProcess.StartInfo.FileName = $"phantomjs.exe所在路径（可以是相对路径）";
pProcess.StartInfo.RedirectStandardOutput = true;
pProcess.StartInfo.UseShellExecute = false;
pProcess.EnableRaisingEvents = false;
//在phantomjs.exe里面执行的命令
pProcess.StartInfo.Arguments = $"Test2.js所在路径（可以是相对路径） {url}";
pProcess.Start();

char[] spliter = { '\r' };
StreamReader sReader = pProcess.StandardOutput;
string[] output = sReader.ReadToEnd().Split(spliter);

foreach (string s in output)
  Console.WriteLine(s);

pProcess.WaitForExit();

//取出计算结果
Console.WriteLine(output[0]);
pProcess.Close();

JS如下：
function Test() {
  //创建phantomjs对象
  var system = require('system');
  //取出参数
  var data = system.args[1];
  console.log(Math.floor(data));
}

Test();
phantom.exit();

//引用：Jint
string filePath = $"{Environment.CurrentDirectory}//ExcuteJs//TestJs.js";
string data1 = "1";
string data2 = "2";
string jsCode = System.IO.File.ReadAllText(filePath);
var square = new Engine()
        .SetValue("data1", data1) // define a new variable
        .SetValue("data2", data2) // define a new variable
        .Execute(jsCode) // execute a statement
        .GetCompletionValue() // get the latest statement completion value
        .ToObject(); // converts the value to .NET
