c# - HttpClient.SendRequestAsync触发StackOverflow

我一直在编码一个库，其中包含从在线服务到存储处理的大多数基本功能，而且我一直陷在一种方法中，该方法应该将图像上传到主机，该主机将返回文件的路径。

问题是当我尝试拨打电话时，由于堆栈溢出，应用程序崩溃了。

这是完整的方法：

public static async Task<WebResult> UploadImage( WebHost webHost, Object webPath, String webQuery, IRandomAccessStream imageStream ) {
    if (!AllowNetworkConnectivity) {
        return new WebResult( false, true, null );
    }

    HttpClient
        httpClient = new HttpClient();

    HttpMultipartFormDataContent
        httpMultipartContent = new HttpMultipartFormDataContent();

    HttpStreamContent
        httpStreamContent = new HttpStreamContent( imageStream );

    httpStreamContent.Headers.Add( "Content-Type", "application/octet-stream" );
    httpMultipartContent.Add( httpMultipartContent );

    try {
        HttpRequestMessage
            httpRequest = new HttpRequestMessage( HttpMethod.Post, new Uri( WebServerUrl( /* ! */ ) ) );

        Dictionary<String, String>
            webCredentialsDictionary = WebServerAuthenticationCredentials( webHost ) as Dictionary<String, String>;

        foreach (KeyValuePair<String, String> credentialEntry in webCredentialsDictionary) {
            httpRequest.Headers.Add( credentialEntry );
        }

        httpRequest.Content = httpMultipartContent;

        /* THE STACK OVERFLOW EXCEPTION IS TRIGGERED HERE */
        HttpResponseMessage
            httpResponse = await httpClient.SendRequestAsync( httpRequest );

        httpResponse.EnsureSuccessStatusCode();

        return new WebResult( true, true, null );
    } catch (Exception exception) {
        AppController.ReportException( exception, "Unable to upload image." );

        return new WebResult( false, true, null );
    }
}

最佳答案

StackOverflowException的起源在这里：

httpMultipartContent.Add( httpMultipartContent );

我向该对象添加了对象，这可以自我说明。我交换了变量，它应该是这样的：

httpMultipartContent.Add( httpStreamContent );
