C # write asynchronous? To achieve the popup window to invoke the web service-CodePudding

In another way so that calls can be called a main implementation when loading wait for window
This. SplashScreenManager1. ShowWaitForm ();

Task Xmlstring=GetPatientList (pid);

This. SplashScreenManager1. CloseWaitForm ();

CodePudding user response:

What should we do with an error?

CodePudding user response:

You this is not a DCLInterface asynchronous method, if the method is an asynchronous method, load before you only need to await the pop-up box, await closed after loading frame,

CodePudding user response:

Give you an asynchronous method

 public static class CallWebAPI 
{
Public static async Task APIPost (url string, the string data) 
{
The string result=string. The Empty; 
//set HttpClientHandler AutomaticDecompression 
(1) {var handler=new HttpClientHandler AutomaticDecompression=DecompressionMethods. GZip}; 
//create the HttpClient (note that the incoming HttpClientHandler) 
Using HTTP=new HttpClient (var (handler)) 
{
//using FormUrlEncodedContent do HttpContent 
Var content=new FormUrlEncodedContent (new Dictionary () 
{
//pass a single value 
{" ", the data}//keys must be empty 
//transfer object 
//{" name ", "hello"}, 
//{" age ", "16"} 
}); 

//await an asynchronous response to 
Var response=HTTP. Await PostAsync (url, the content); 
//to ensure the success of the HTTP status value 
The response. EnsureSuccessStatusCode (); 
//await asynchronous read last JSON (note that the gzip automatically extract had been made, and because of the above AutomaticDecompression=DecompressionMethods. Gzip) 
Result=await the response. The content. ReadAsStringAsync (); 
} 
return result; 
} 

The static async void APIGet (string url) 
{
//create the HttpClient (note that the incoming HttpClientHandler) 
(1) {var handler=new HttpClientHandler AutomaticDecompression=DecompressionMethods. GZip}; 

Using HTTP=new HttpClient (var (handler)) 
{
//await an asynchronous response to 
Var response=HTTP. Await GetAsync (url); 
//to ensure the success of the HTTP status value 
The response. EnsureSuccessStatusCode (); 

//await asynchronous read last JSON (note that the gzip automatically extract had been made, and because of the above AutomaticDecompression=DecompressionMethods. Gzip) 
Console. WriteLine (await the response. The content. ReadAsStringAsync ()); 
} 
} 
}

refer to the second floor morning to evening reply:

DCLInterface is a web service method

CodePudding user response:

DCLInterface not asynchronous method, cannot use await, you can then use the async DCLInterface do the encapsulation, again to encapsulate function USES await,

Ps: loading window with asynchronous relationship? Not all scenarios should use asynchronous, otherwise easy to simple complication,
