Install the package

        NetcodeHub.Packages.Components.FileUpload

Add the package namespace to the project

         @using NetcodeHub.Packages.Components.FileUpload

Use the component

          <NetcodeHubFileUpload @ref="FileUploadComponent" 
                                Notify="RetrieveContent" 
                                Multiple=true  // You can specify or leave empty to accept one file.
                                RequiredExtensions="RequiredEx"/>
          <h1>@Errors</h1>

     @code {
     List<string> RequiredEx = [".jpg", ".png", ".jpeg", ".gif"];
        
        NetcodeHubFileUpload? FileUploadComponent;

Grabing only Single Image (Multiple Section = false) in Base64String.

        string? Errors;
        string Base64String = string.Empty;
        void RetrieveContent(FileModel incomingFiles)
        {
            if(incomingFiles is not null)
            {
                foreach (var item in incomingFiles.IBrowserFiles!)
                {
                    // This is for single.
                    var getFileNameAndBase64String = incomingFiles.BaseFiles!.FirstOrDefault(_ => _.Key.Equals(file.Name, StringComparison.OrdinalIgnoreCase));

                    if (getFileNameAndBase64String.Key != null)
                        Base64Image = getFileNameAndBase64.Value;
                }
            }
            Errors = FileUploadComponent!.GetErrors();
        }
    }
       

If you need the original file, then :

void RetrieveContent(FileModel incomingFiles)
        {
            if(incomingFiles is not null)
            {
                foreach (var item in incomingFiles.IBrowserFiles!)
                {
                    // This is for single.
                    var orignalFile = item;
                }
            }
            Errors = FileUploadComponent!.GetErrors();
        }
    }
