Já používám ImageCropper
a MediaPlugin
Nahrát obrázky. Nicméně mám problém dostat se na obrázek po oříznutí obrazu.
string imagefile;
protected void OnClickedRectangle(object sender, EventArgs e)
{
new ImageCropper()
{
Success = (imageFile) =>
{
Device.BeginInvokeOnMainThread(() =>
{
view_imageavatar.Source = ImageSource.FromFile(imageFile);
});
}
}.Show(this);
}
async void edit_avatar_Tapped(object sender, EventArgs e)
{
try
{
await CrossMedia.Current.Initialize();
new ImageCropper()
{
PageTitle = "Title",
AspectRatioX = 1,
AspectRatioY = 1,
CropShape = ImageCropper.CropShapeType.Rectangle,
SelectSourceTitle = "Img",
TakePhotoTitle = "Take Camera",
PhotoLibraryTitle = "Img Gallery",
Success = (imageFile) =>
{
Device.BeginInvokeOnMainThread(async() =>
{
view_imageavatar.Source = ImageSource.FromFile(imageFile);
imagefile = imageFile;
//API Get Images Upload
var content = new MultipartFormDataContent();
content.Add(new StreamContent(imageFile), "files", imagefile);
var httpClient = new HttpClient();
var responses = await httpClient.PostAsync("https://xxxxx/api/Upload", content);
});
}
}.Show(this);
}
catch (Exception ex)
{
System.Diagnostics.Debug.WriteLine("GalleryException:>" + ex);
}
}
Nicméně, jak mohu získat Obrázek, který chcete nahrát. všimněte si, že view_imageavatar
stále zobrazuje snímek po oříznutí. Tks!
Aktualizace...
async void edit_avatar_Tapped(object sender, EventArgs e)
{
try
{
await CrossMedia.Current.Initialize();
new ImageCropper()
{
PageTitle = "Title",
AspectRatioX = 1,
AspectRatioY = 1,
CropShape = ImageCropper.CropShapeType.Rectangle,
SelectSourceTitle = "Img",
TakePhotoTitle = "Take Camera",
PhotoLibraryTitle = "Img Gallery",
Success = (imageFile) =>
{
Device.BeginInvokeOnMainThread(async() =>
{
view_imageavatar.Source = ImageSource.FromFile(imageFile);
imagefile = imageFile;
//API Get Images Upload
var fileStream = File.OpenRead(imageFile);
var fileContent = new StreamContent(fileStream);
var content = new MultipartFormDataContent();
content.Add(fileContent, "files", imageFile);
var httpClient = new HttpClient();
var responses = await httpClient.PostAsync("https://xxxxxx/api/UploadAvatarUs", content);
});
}
}.Show(this);
}
catch (Exception ex)
{
System.Diagnostics.Debug.WriteLine("GalleryException:>" + ex);
}
}
To stále nefunguje?

async void edit_avatar_Tapped(object sender, EventArgs e)
{
try
{
await CrossMedia.Current.Initialize();
new ImageCropper()
{
PageTitle = "Title",
AspectRatioX = 1,
AspectRatioY = 1,
CropShape = ImageCropper.CropShapeType.Rectangle,
SelectSourceTitle = "Img",

view_imageavatar.Source = ImageSource.FromFile(imageFile);
imagefile = imageFile;
//API Get Images Upload
var upfilebytes = File.ReadAllBytes(imageFile);
var ms = new MemoryStream(upfilebytes);
var content = new MultipartFormDataContent();
content.Add(new StreamContent(ms), "files", imageFile);
var httpClient = new HttpClient();
var responses = await httpClient.PostAsync("https://xxxxxx/api/UploadAvatarUs", content);
});
}
}.Show(this);
}
catch (Exception ex)
{
System.Diagnostics.Debug.WriteLine("GalleryException:>" + ex);
}
}
-> To pořád nemůžu nahrát fotky přes API?
Nicméně se snažím nepoužívat ImageCropper. Nahrát přímo.
async void edit_avatar_Tapped(object sender, EventArgs e)
{
var file = await MediaPicker.PickPhotoAsync();
var content = new MultipartFormDataContent();
content.Add(new StreamContent(await file.OpenReadAsync()), "files", file.FileName);
var httpClient = new HttpClient();
var responses = await httpClient.PostAsync("https://xxxxxx/api/UploadAvatarUs", content);
string a = responses.StatusCode.ToString();
}
--> Pak to funguje dobře, obraz je nahrán přes rozhraní API
Má image zatížení z content.Add(new StreamContent(ms), "files", imageFile);
to nebude fungovat s API? Hledal řešení z každého.
File.Open(imageFile);
->Open
nefunguje. Jsem se projít vFile.OpenRead(imageFile)
. Je to dobré? Mám aktualizováno výše.
