When posting data from view, I send it to the Controller via ajax and split the date time value, then the parameter becomes a string and I want to convert it to my datetime, but I encounter such an error
There is a blank/space at the end of your 'date' string. Use bgdate.Trim(). You may also check that bgdate is a non null string and have then a default value with something like (bgdate == null)?"01-01-1970":bgdate.Trim().
There's a white space in your value 08-04-2021 . You should Trim() it:
bgdate.Trim()

The testCards string picks up the value from web.config. But every time I try to use int.tryParse it gives a false value when I try to parse the string testCards. Any idea what I might be missing?
<add key ="TestCards" value ="4987654321098769,4111111111111111,4987654321098769"/>
string testCards = ConfigurationManager.AppSettings["TestCards"];
int flag=0
bool isSuceeded=false
isSuceeded = int.TryParse(testCards, out flag);
It's not an int! It has commas in it, and if it didn't have commas the number is much bigger than an int can hold in any .NET platform.
I'm gathering from the name TestCards that these are intended to be credit card numbers? In that case they should be strings.

An public string ItemSubType which is assigned a string "primary" by another script is somehow not equal to the string "primary". I've checked for empty characters but there isn't any. I've been absolutly stumped by this but also interested in how this is happening.
Debug.Log("---primary---");
Debug.Log("---" + ItemSubType + "---");
if(ItemSubType != "primary")
{
Debug.Log("This is ridiculous!");
}
Here is logs:A picture of the log
Thank you all for the comments!
After browsing through some other questions, I found .Trim().
Mystically there seems to be an invisible character in the string that isn't a whitespace character, as would be evident by the lack of spaces when adding '---' to either side.
By doing this:
ItemSubType = ItemSubType.Trim();
It fixed the Issue. To give some context, I pulled the string data from a csv file. I checked the file for any extra spaces but there wasn't any. Not sure if this is related tho.

I have an oData api url where I am trying to replace querystring values with dynamic values.
I wish to pass comma separated string to one of my placeholder but I am getting error:
"Input string is not in correct format".
Here, in my "$select" placeholder I am passing comma separated string but it's failing with above error.
Here is my code:
string test = string.Format("https://myapiUrl/views/my_view_name?$filter=customer_id eq {} & $select={}", "101", "price,createdOn");
Can anybody guide me on this ?
Thanks !!!
string test = string.Format("https://myapiUrl/views/my_view_name?$filter=customer_id eq {0} & $select={1}", "101", "price,createdOn");
Have to add the number of the index of the parameter to the curly braces. (zero based)

I'm using LINQ to read in some XML and then use that to set properties in an object. The XML looks like this:
<display_location>
<full>London, United Kingdom</full>
<city>London</city>
<state/>
<state_name>United Kingdom</state_name>
<country>UK</country>
<country_iso3166>GB</country_iso3166>
<zip>00000</zip>
<magic>553</magic>
<wmo>03772</wmo>
<latitude>51.47999954</latitude>
<longitude>-0.44999999</longitude>
<elevation>24.00000000</elevation>
</display_location>
And the code I have is:
select new Forecast
{
//Set properties for the display location
DisplayLatitude = (double)i.Element("display_location").Element("latitude"),
DisplayLongtitude = (double)i.Element("display_location").Element("longtitude"),
DisplayElevation = (string)i.Element("display_location").Element("elevation"),
};
I can correctly set the latitude and elevation however I'm getting the exception "Value cannot be null" when I try to parse the longtitude.
I think it might be because of the negative symbol. How do I fix this?
It's "longitude", not "longtitude". Your string needs to exactly match the XML element name or you'll get a null value instead.

Well, I need to subtract the number from a string, and in the end she should continue being a string ...
I try:
PStruct.character[Index, PStruct.player[Index].SelectedChar].Y =
(Convert.ToInt32(PStruct.character[Index, PStruct.player[Index].SelectedChar].Y) - 1)
.ToString;
Character.Y is a string.
The error:
Cannot convert method group "ToString" to non-delegate type "string".
Anyone have tips or a solution?
Use parenthesis to invoke/call a method:
expr.ToString()
Without parenthesis it (ToString) is treated as a "method group", which is useful in some cases - but not here.
As written, you are trying to treat a function ToString as a type string.
As the comment mentioned, you probably meant to write ToString().
