如果想要自己在C#中拼接的话

string script = @"
var control=
$('.blueimp-file-upload-submit').on('click',function(e) {
e.preventDefault();
e.stopPropagation();
var previews = $('.preview');
$.each(previews, function(){
var data = $(this).data('data');
data.submit();
});
WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions(`""${this.name}""`, """", true, ""Action"", """", false, false));
});";
