Class UploadFiles

Represents the details of uploaded files in the SfUploader component.

Inheritance

System.Object

UploadFiles

Namespace: Syncfusion.Blazor.Inputs

Assembly: Syncfusion.Blazor.dll

Syntax

public class UploadFiles : Object

Remarks

This class encapsulates comprehensive information about files that have been uploaded through the uploader component. It provides access to both the file metadata and the actual file content, enabling developers to process uploaded files, save them to storage, or perform validation and manipulation operations on the uploaded data.

Constructors

UploadFiles()

Declaration

public UploadFiles()

Properties

File

Gets the browser file data representing the uploaded file from the SfUploader component.

Declaration

public IBrowserFile File { get; }

Property Value

Type	Description
Microsoft.AspNetCore.Components.Forms.IBrowserFile	An Microsoft.AspNetCore.Components.Forms.IBrowserFile object representing the uploaded file, or null if no file is available.

Remarks

The File property is used to handle file uploads in Blazor applications. It represents the file selected by the user in the browser and provides access to the file's metadata, such as the file name, size, and content type. To read the contents of the uploaded file, call the OpenReadStream() method of the Microsoft.AspNetCore.Components.Forms.IBrowserFile interface, which returns a stream that you can use to read the file data. This is the recommended approach for accessing file content in modern implementations.

Examples

The following example demonstrates how to handle file uploads and save them to disk:

<SfUploader AutoUpload="true">
    <UploaderEvents ValueChange="@OnChange"></UploaderEvents>
</SfUploader>
@code{
    private async Task OnChange(UploadChangeEventArgs args)
    {
        try
        {
            foreach (var file in args.Files)
            {
                var path = @"D:\" + file.FileInfo.Name;
                FileStream filestream = new FileStream(path, FileMode.Create, FileAccess.Write);
                await file.File.OpenReadStream(long.MaxValue).CopyToAsync(filestream);
                filestream.Close();
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
        }
    }
  }

FileInfo

Gets the detailed information about the selected file.

Declaration

public FileInfo FileInfo { get; }

Property Value

Type	Description
FileInfo	A FileInfo object containing comprehensive file details, or null if no file information is available.

Remarks

This property provides access to comprehensive metadata about the uploaded file, including name, size, type, upload status, and other properties. This information is essential for file validation, processing decisions, and user interface updates.

Stream

Gets the memory stream containing the selected file data.

Declaration

public MemoryStream Stream { get; }

Property Value

Type	Description
System.IO.MemoryStream	A System.IO.MemoryStream containing the file data, or null if no stream is available.

Remarks

This property provides access to the file content as a memory stream. Note: This property is obsolete and will be removed in a future version. Use the File property instead to access the uploaded file's stream through the OpenReadStream() method.
