嗨,我想存儲在SQL數據庫表中的Excel文件,但我有我的代碼在服務器端C#一些麻煩。 所以事情是,我採取了所有我需要的值,但其中一個是實際的Excel文件。所以我有兩個問題:
1)我可以通過使用varbinary(max)數據類型在表中正確存儲excel的文件。
2)如果是這樣,我如何通過ajax將該文件傳遞給我的服務器代碼?正如我趕上用戶在js文件我不是很肯定的我可以處理它在C#
這裏是我的代碼:在AJAX和ASP.NET的SQL數據庫中插入Excel文件
<script>
function tryme() {
var modelx = new Object();
var depS = document.getElementById("resultDep");
var catS = document.getElementById("resultCat");
var schemS = document.getElementById("schemes");
var wiw = document.getElementById("wiw").value;
modelx.wiw = wiw;
var nm = document.getElementById("namePro").value;
modelx.name = nm;
var dp = depS.options[depS.selectedIndex].value;
modelx.dep = dp;
var ct = catS.options[catS.selectedIndex].value;
modelx.cat = ct;
var sch = schemS.options[schemS.selectedIndex].value;
modelx.schem = sch;
var myFile = $('#fileinput').prop('files');
modelx.f = myFile;
alert("../"+ modelx.name +"/" + modelx.cat + "/" + modelx.dep + "/" + modelx.schem
+ "/" + modelx.wiw + "/" +modelx.f);
$.ajax({
type: "POST",
dataType: "json",
contentType: "application/json; charset=utf-8",
url: '@Url.Action("CreateRequest", "Home")',
data: "{'Name':'" + modelx.name + "', 'Category':'" + modelx.cat + "',"+
"'Department':'" + modelx.dep + "' ," + "'Wiw':'" + modelx.wiw + "',"+
"'Scheme':'" + modelx.schem + "' ," + "'File':'" + modelx.f + "'"
+ "}",
success: function (Record) {
},
Error: function (textMsg) {
alert("something got wrong");
}
});
//end function
}
</script>
<script src="~/Scripts/jquery-1.10.2.js"></script>
<script src='http://code.jquery.com/jquery-latest.min.js' type='text/javascript'></script>

)

嗨,我查找HttpPostedFileBase我發現了一些方法來存儲文件的**路徑**和存儲在服務器的文件夾中的文件,但我想存儲我的文件在SQL基地使用queryi' m使用** varbinary **數據類型來存儲在sql中 –
