如果存在相同的名称,是否有任何方法可以替换文件？我在Azure存储中看不到任何替换方法.这是我的代码：
var client = new CloudBlobClient(
new Uri(" http://sweetapp.blob.core.windows.net/"),credentials);
var container = client.GetContainerReference("cakepictures");
await container.CreateIfNotExistsAsync();
var perm = new BlobContainerPermissions();
perm.PublicAccess = BlobContainerPublicAccessType.Blob;
await container.SetPermissionsAsync(perm);
var blockBlob = container.GetBlockBlobReference(newfilename + i + file.FileType);
using (var fileStream = await file.OpenSequentialReadAsync())
{
await blockBlob.UploadFromStreamAsync(fileStream);
}
