String s ="";
int? nullint = s ( How to convert "String s" to "nullable int")
|

First, I'd avoid nulls unless absolutly neccesary, the can cause all sorts of problems if they are not coded against.
The exact code you need depends upon your desired "failure mode" (see comment in block) but here is an answer:
static int? Convert (string value)
{
if (string.IsNullOrEmpty(value))
return null;
int returnedInt;
if (int.TryParse(value, out returnedInt))
return returnedInt;
return null;
}
also IMO nullint is a shoud be renamed as it has both "null" and "int" in it, as well as not being very descriptive.
[Edit]
Nuri Ismails post (below) achieves the same as the above, but is more compact, so I'd use that in preference.

How about something like this:
public int? ToNullableInt32(string s)
{
int i;
return (Int32.TryParse(s, out i)) ? i : null;
}
String s ="";
int? nullint = ToNullableInt32(s);

Hi,
In my program i'm trying to access a server drives details from my machine with different username and password, for this i'm using the connections options class in C#,
here is the code i'm using
try
{
ConnectionOptions opt = new ConnectionOptions("MS_409", "USERNAME", "PASSWORD", "ntdlmdomain:DOMAIN", ImpersonationLevel.Impersonate, AuthenticationLevel.Default,false, null, TimeSpan.MaxValue);
ObjectQuery query = new ObjectQuery("SELECT FreeSpace, Name FROM Win32_LogicalDisk WHERE DriveType = 3");
ManagementScope scope = new ManagementScope("\\\\" + "16.106.64.108" + "\\root\\cimv2", opt);
ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query);
ManagementObjectCollection coll = searcher.Get();
foreach (ManagementObject ms in coll)
{
Console.WriteLine(ms["Name"]);
Console.WriteLine(Convert.ToDecimal(ms["FreeSpace"]) / 1024 / 1024 / 1024);
}
}
catch (Exception e)
{
Console.WriteLine(e.Message);
}
whenever i reach line "ManagementObjectCollection coll = searcher.Get();" i'm getting the "Invalid Parameter" error, i could not find a slution for this, please help.
Thanks,

Don't you have to change the value "ntdlmdomain:DOMAIN" also to a valid domain on the remote machine?
Sorry thats the only idea I have. Everything else seems to be right and your query works also on my system.

Thanks for your reply covean,
I changed the value from "ntdlmdomain:DOMAIN" to "ntdlmdomain:AMERICAS", but still it is also not working.
Thanks,

You may wish to customize your setup code a little, perhaps you can use this tutorial and add shortcut & checkbox yourself... link[^]

Hi. I just need help on whats the most commonly used LISP programming software and where can i possibly find an installer for that. I just need it for my class that discusses about STRUCTURE OF PROGRAMMING LANGUAGES and our project is that we need to compare a program created in LISP and in C#. C# is the main programming language that is currently taught in our school and our professor's objective is to let us learn new programming languages besides C# and to see the advantages and disadvantages of both programming languages.
Can someone help me? I'm currently confused because when I tried to search for LISP programming languages I can't determine which is commonly used and what's not.
Please consider my post even if it's not really related to C# programming. Thank you.

Hello Experts,
I would like to use
object System.Xml.Serialization.XmlSerializer.Deserialize(System.IO.StreamReader stream) within a constructor
public class MyObject()
{
public MyObject (string fileName)
{
System.IO.StreamReader readingStream = new System.IO.StreamReader(fileName);
System.Xml.Serialization.XmlSerializer readingSerializer = new System.Xml.Serialization.XmlSerializer(typeof(MyObject));
MyObject justRead = (MyObject)readingSerializer.Deserialize(readingStream);
}
}But I don't know what to do with justRead.
Of course, I could just forget about the constructor and use a method
public static MyObject Load (string fileName)
But is it really impossible to create something usable like this one?
MyObject iLoadedThisFromFile = new MyObject (storageFileName);
Ciao,
luker

The easiest way would be to copy the variables of justRead to the variables of your new class.
Example:
this.Prop1 = justRead.Prop1;
this.Prop2 = justRead.Prop2;
...
this.PropN = justRead.PropN;
So you construct your new class out of an old class of the same type (works teh same like a copyconstrutor).
Hope that helps.
Greetings

Hi,
I have a stored proc that at the end executes the following line:
Select @ID
In my C# I have the following to try and grab it:
SqlParameter AgentID = new SqlParameter("@ID", SqlDbType.Int, 4);
AgentID.Direction = ParameterDirection.ReturnValue;
sqlCmd.Parameters.Add(AgentID);
int NewAgentID = 0;
try
{
sqlCon.Open();
sqlCmd.ExecuteScalar();
sqlCon.Close();
NewAgentID = int.Parse(sqlCmd.Parameters["@ID"].Value.ToString());
return NewAgentID;
}
In debug this seems to set NewAgentID to -1, however it should be a legitimately returned variable from the stored proc, any ideas what is wrong?

You need to get C# to excute your stored procedure then get the return variable and store it in NewAgentID.
I use Microsoft Database access application block. So in c# the code would look somehting like this.
int NewAgentId = int.Parse(SqlHelper.ExecuteScalar(ConnectionString, CommandType.StoredProcedure, "Call for Stored Procedure").ToString());

This means that you are returning the value of @ID. try some thing like this
sqlCon.Open();
object result = sqlCmd.ExecuteScalar();
sqlCon.Close();
if (result != null)
NewAgentID = int.Parse(result.ToString());
