如何在异步方法完成之前返回我的视图 [英] How can I return my view until my async methode finish

问题描述

i有一个Async方法，我想把它叫做我在行动中添加的相同特征，我的问题是我返回查看时methode在后台保持runnig并且视图是空的



我尝试过：



i试试，



公共ActionResult loaddata（）

{

任务任务=新任务（WsdlCompareAsync）;

task.Start（）;





返回Json（new {data = myListDisp}，JsonRequestBehavior.AllowGet）;

}

静态列表< tracking> myListDisp = new List< tracking>（）;



private async void WsdlCompareAsync（）

{

< br $>


string userName，token，scopePath，apiVersion，defaultCollectionUrl，firstEnvironmentToCompare，secondEnvironmentToCompare;

GetConfiguration（out userName，out token，out scopePath，out apiVersion，out defaultCollectionUrl，out firstEnvironmentToCompare，out secondEnvironmentToCompare）;



WsdlDiff diff = new WsdlDiff（defaultCollectionUrl，userName，token，scopePath，apiVersion）;

myListDisp = await diff.Compare（firstEnvironmentToCompare，secondEnvironmentToCompare）;



}





WsdlCompareAsync在backgroude中运行我已添加静态监听，看看方法是否有效，当我刷新视图cantain数据时

解决方案

您必须按以下方式使用。让我知道

  public   async 任务< ActionResult> loaddata（）
 {
 List myListDisp =  await  WsdlCompareAsync（）; 
  return  Json（ new  {data = myListDisp}，JsonRequestBehavior.AllowGet）; 
} 
 
 
 私人  async 任务< List> ; WsdlCompareAsync（）
 {
  string  userName，token，scopePath，apiVersion，defaultCollectionUrl，firstEnvironmentToCompare，secondEnvironmentToCompare; 
 GetConfiguration（ out  userName， out  token， out  scopePath， out  apiVersion， out  defaultCollectionUrl， out  firstEnvironmentToCompare， out  secondEnvironmentToCompare）; 
 
 WsdlDiff diff =  new  WsdlDiff（defaultCollectionUrl，userName，token，scopePath，apiVersion）; 
  return   await  diff.Compare（firstEnvironmentToCompare，secondEnvironmentToCompare）; 
 
} 

hi,

i have an Async methode and i want to call it to make same traitment i have added in my action, my issue is whene i return view the methode stay runnig in background and the view is empty

What I have tried:

i have try,

public ActionResult loaddata()
{
Task task = new Task(WsdlCompareAsync);
task.Start();


return Json(new { data = myListDisp }, JsonRequestBehavior.AllowGet);
}
static List<tracking> myListDisp = new List<tracking>();

private async void WsdlCompareAsync()
{


string userName, token, scopePath, apiVersion, defaultCollectionUrl, firstEnvironmentToCompare, secondEnvironmentToCompare;
GetConfiguration(out userName, out token, out scopePath, out apiVersion, out defaultCollectionUrl, out firstEnvironmentToCompare, out secondEnvironmentToCompare);

WsdlDiff diff = new WsdlDiff(defaultCollectionUrl, userName, token, scopePath, apiVersion);
myListDisp= await diff.Compare(firstEnvironmentToCompare, secondEnvironmentToCompare);

}


the WsdlCompareAsync stay runing in backgroude i have add static liste to see if the methode work, whene i refresh the view cantain data

解决方案

You have to use in the following way. Let me know

public async Task<ActionResult> loaddata()
{
List myListDisp = await WsdlCompareAsync();
return Json(new { data = myListDisp }, JsonRequestBehavior.AllowGet);
}


private async Task<List> WsdlCompareAsync()
{
string userName, token, scopePath, apiVersion, defaultCollectionUrl, firstEnvironmentToCompare, secondEnvironmentToCompare;
GetConfiguration(out userName, out token, out scopePath, out apiVersion, out defaultCollectionUrl, out firstEnvironmentToCompare, out secondEnvironmentToCompare);

WsdlDiff diff = new WsdlDiff(defaultCollectionUrl, userName, token, scopePath, apiVersion);
return await diff.Compare(firstEnvironmentToCompare, secondEnvironmentToCompare);

}
