C# - Can Convert To The String But Can't Convert Back
Jul 30, 2010
I have a string I need to convert back to a date. I can call .ToString("yyyyMMdd") and get the string i want. My question is how can I convert that back into a date? I'm trying something like the following with no luck.
DateTime d;
var formatInfo = new DateTimeFormatInfo {ShortDatePattern = "yyyyMMdd"};
if (DateTime.TryParse(details.DetectionTime.Date, formatInfo, DateTimeStyles.None, out d))
{
lit.Text = d.ToShortTimeString(); //would like 07/30/2010 as the text
}
I've never used DateTimeFormatInfo before if that isn't obvious. Can someone point me in the right direction. I know I could probably use substring and create a new DateTime(y, m, d) etc... I'm just wondering since c# interpreted .ToString() correctly, if it can't derive a date from the very same string it output.

I know it sounds crazy, but yes, I am hoping to convert a site that was developed for 3.5 back to 1.1. In Visual Studio, I can target the output to 2.0, but that's as far back as it goes. I assume there is some way to do this, but I've been up for too long to even begin to think clearly and the only info I can find by searching here or google is for converting from old to new, not the other way around.

on VWD 2005 this code works fine, but on 2008 it says I haven't created an instance of the object. I want to convert the object connString (a connection string) into a string.
'This acceses the virtual directory web.config file for connection strings
'We have to convert the object to a connection string
Dim rootWebConfig As System.Configuration.Configuration
rootWebConfig = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("/VirtualDirec")
Dim connString
As System.Configuration.ConnectionStringSettings
connString = rootWebConfig.ConnectionStrings.ConnectionStrings("ConnectString1")
Dim strConnString
As
String = connString.ToString().......

I have project in development where string operations like "Hi " + variable + ", welcome to Project" are used at many places (given example is very minor one).
One of the requirement is to convert it to string.format style.
It is very long and tedious job, where I would not like to break earlier working code due to any human error might happen while converting it.
I would like to if any Macro or VS command which I can create to handle it. Just like we mark block of code and do Extract function in Re-factor options.

I'm trying to convert a string to decimal but I get this exception:
Exception Details:
Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: 'string' does not contain a definition for 'AsDecimal'
Here is the code:
decimal PriceHT = 0;
var PriceRequest= "SELECT * FROM Price_" + HttpContext.Current.Session["PriceTableId"] ;
foreach (var Price in Database.OpenFile("Base.sdf").Query(PriceRequest)){
PriceHT = PrixceHT + (Price.PT).AsDecimal(); //Price.PT returns a string
}

Lots of people recommend to wrap the MVC JsonReturn result in a textarea to play nicely with jquery forms etc.
That part makes sense but how do I get the json object back in my client jquery code?
The client jquery plugin should look something like this:
// Doesn't work since data is "<textarea>{"error":true,"msg":"foo"}

i want to check only if the column Active is Yes, then get into the if loop. But it gives me an error "Cannot convert from string to int" for the last condition in if. What do you guys i can do.
if (ds != null && ds.Tables != null
&& ds.Tables.Count > 0
&& ds.Tables[0].Rows.Count > 0
&& ds.Tables[0].Columns[0].ColumnName["Status"] == "Y")
{
disableloc.DataSource = ds;
disableloc.DataBind();
}
else
{
ds = null;
disableloc.DataSource = ds;
disableloc.DataBind();
The stored procedure is SELECT ML.locationname,
rtrim(ML.address) + (CASE WHEN ML.Address2 IS NOT NULL THEN ('' '' + rtrim(ML.Address2)) ELSE '''' END) + '' - ''+ ML.city + '', ''+ ML.state as address,
ML.locationid,
ML.merchantid,
case when ML.active <> ''Y'' then ''Deactive'' else ''Active'' end [Status],
(SELECT count(*) as retval
FROM merchant_statistics
WHERE type = ''merchant''
AND locationID= ML.LocationID
AND status = ''clicked'') as stat,
'' '' as button,'' '' as blank ,
dbo.GetCouponCountForLocations(@_merchantid,ML.locationID) couponCount,
MP.DomainName,
(SELECT Count(*) FROM Promotion WHERE LocationId = ML.locationid AND PostType = 1) AS jobs
FROM merchant_location ML , Merchant_Pages MP
WHERE MP.LocationID = ML.LocationID
AND ML.merchantid = @_merchantid Order By '

I am trying to convert a field from a string to an int, then pass it to a query using tableadapters. I have the following function:
protected String countResponses(String value)
{
String input = value.ToString();
int fordb = Int32.Parse(input);
FrontendTableAdapters.ForumTableAdapter ta = new FrontendTableAdapters.ForumTableAdapter();
DataTable table = ta.CountPosts(value);
if (table.Rows.Count > 0)
{
return table.Rows[0].ItemArray[1].ToString();
}
else
{
return "Unknown";
}
}
It is working greate up to putting it in CountPosts() where I get the following error: Error 4Cannot implicitly convert type 'object' to 'System.Data.DataTable'. An explicit conversion exists (are you missing a cast?) :UsersDaveDesktopWebAppsFigmentvilleFigmentvilleyoursayDefault.aspx.cs 49 31 I think this is because it is looking for an int. But haven't I already converted it to an int?

I am getting DateString in JavaScript from the TextBox like,
var dateString = document.getElementById('<%= txtEffDate.ClientID %>').value;
dateString value may be in following format.
en-US -> "4/29/2010"
fr-FR -> "29/04/2010"
de-DE -> "29.04.2010"
it-IT -> "29/04/2010"
es-ES -> "29/04/2010"
zh-CN -> "2010/4/29"
ja-JP -> "2010/04/29"
sv-SE -> "2010-04-29"
And converting this to Date Object as follows,
var d1 = new Date(dateString);
though its giving me the wrong result like for fr-FR "29/04/2010" ==> "Fri May 4 00:00:00 UTC+0530 2012"
Which is completely irrelevant, How should I get the correct Date ?
I have also set < globalization culture="auto" /> in web.config & < asp:ScriptManager ID="scr1" runat="server" EnableScriptGlobalization="true"/>
