{
    string filePath = "指定的服务器文件路径";
    File.WriteAllBytes(filePath, imageBytes);
}

function uploadImage() {
    var fileInput = document.getElementById("fileUpload");
    var file = fileInput.files[0];
    
    var reader = new FileReader();
    reader.onloadend = function() {
        var imageBytes = new Uint8Array(reader.result);
        
        // 调用Web Services方法上传图像
        YourWebService.UploadImage(imageBytes);
    };
    
    reader.readAsArrayBuffer(file);
}
