JavaScriptSerializer().Serialize(Entity Framework object)
- by loviji
May be, it is not so problematic for you. but i'm trying first time with json serialization. and also read other articles in stackowerflow.
I have created Entity Framework data model.
then by method get all data from object:
private uqsEntities _db = new uqsEntities();
//get all data from table sysMainTableColumns where tableName=paramtableName
public List<sysMainTableColumns> getDataAboutMainTable(string tableName)
{
return (from column in _db.sysMainTableColumns
where column.TableName==tableName
select column).ToList();
}
my webservice:
public string getDataAboutMainTable()
{
penta.DAC.Tables dictTable = new penta.DAC.Tables();
var result = dictTable.getDataAboutMainTable("1");
return new JavaScriptSerializer().Serialize(result);
}
and jQuery ajax method
$('#loadData').click(function() {
$.ajax({
type: "POST",
url: "WS/ConstructorWS.asmx/getDataAboutMainTable",
data: "{}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(msg) {
$("#jsonResponse").html(msg);
var data = eval("(" + msg + ")");
//do something with data
},
error: function(msg) {
}
});
});
problem with data, code fails there. and i think i'm not use JavaScriptSerializer().Serialize() method very well.
Please, tell me, what a big mistake I made in C# code?
