How to save Zip file on local machine which is coming from HttpClient using SaveFileDialog in Windows application using C#?
To save a Zip file received from an HttpClient
using SaveFileDialog
in a Windows application using C#, you can follow these steps:
- Add necessary namespaces: Add the following namespaces at the top of your C# file:
csharpusing System.Net.Http;
using System.IO;
using System.Windows.Forms;
- Create an instance of
HttpClient
and send a GET request to retrieve the Zip file:
csharpusing (HttpClient client = new HttpClient())
{
HttpResponseMessage response = await client.GetAsync(zipFileUrl);
response.EnsureSuccessStatusCode();
// Read the Zip file content
byte[] zipBytes = await response.Content.ReadAsByteArrayAsync();
// ...
}
Replace zipFileUrl
with the URL or URI from where you are downloading the Zip file.
- Open a
SaveFileDialog
to prompt the user for the save location:
csharpSaveFileDialog saveFileDialog = new SaveFileDialog();
saveFileDialog.Filter = "Zip Files (*.zip)|*.zip";
saveFileDialog.FileName = "downloaded.zip";
if (saveFileDialog.ShowDialog() == DialogResult.OK)
{
string savePath = saveFileDialog.FileName;
// ...
}
This code sets the filter to only show Zip files and sets the default filename as "downloaded.zip". If the user selects a save location and clicks OK, the selected path will be available in the savePath
variable.
- Save the downloaded Zip file using the selected path:
csharpFile.WriteAllBytes(savePath, zipBytes);
This code saves the downloaded Zip file to the selected path using the File.WriteAllBytes
method.
Here's the complete code snippet:
csharpusing System.Net.Http;
using System.IO;
using System.Windows.Forms;
private async void DownloadAndSaveZipFile()
{
using (HttpClient client = new HttpClient())
{
HttpResponseMessage response = await client.GetAsync(zipFileUrl);
response.EnsureSuccessStatusCode();
byte[] zipBytes = await response.Content.ReadAsByteArrayAsync();
SaveFileDialog saveFileDialog = new SaveFileDialog();
saveFileDialog.Filter = "Zip Files (*.zip)|*.zip";
saveFileDialog.FileName = "downloaded.zip";
if (saveFileDialog.ShowDialog() == DialogResult.OK)
{
string savePath = saveFileDialog.FileName;
File.WriteAllBytes(savePath, zipBytes);
MessageBox.Show("Zip file saved successfully!");
}
}
}
Remember to replace zipFileUrl
with the actual URL or URI of the Zip file you want to download.
This code downloads the Zip file using HttpClient
, prompts the user to select a save location using SaveFileDialog
, and then saves the file using File.WriteAllBytes
. Finally, a message box is displayed to indicate that the file has been saved successfully.
Make sure to handle exceptions and implement appropriate error handling based on your specific requirements.
