String and string?
Hi guys,
I was wondering the difference between small letter string type and a capital letter String type. Does anyone know about this? Highly appreciate for your answers! Thankz!
The "proper" version is String, as it references the System.String class of the .NET Framework Class Library.
The ability to use string is provided by C#, where it is an alias to String.
Similarly, the "proper" version of an integer is Int32, as it references System.Int32. The ability to use int is provided by C#, and the ability to use Integer is provided by VB.NET, and both int and Integer are aliases...
string to string[]
Hi,
I've got this code :
string[] Params;
string SQL = "SELECT * FROM T_MANAGEMENT_PAGES";
SqlCommand myCommand = new SqlCommand(SQL, myConnection);
myConnection.Open();
SqlDataReader myReader = myCommand.ExecuteReader();
try
{
while (myReader.Read())
{
Params_Type = myReader.GetValue(0).ToString();
}
}
catch
{
}
finally
{
}
myReader.Close();
My problem is to obtain Params_Type.
But each time, it says : "impossible to convert '[object]' in 'string[]' &quo...

"String[10]" is a fixed-length, statically allocated, Ansi-based ShortString.
"String" is a dynamic-length, dynamically allocated, reference counted, Ansi-based
or Unicode-based (depening on Delphi version) Long string.
Unless you absolutely need the static, fixed length nature of ShortString,
such as in records that interact with external systems, you should stay ...
string() = string()

Dim Items(), Other() As String
Items = New String() {"A","B","C"}
Other = New String() {}

how can I get all the values ?

Hi,
If I understand your requirement correctly, this should do it
Dim Items() As String = {"A", "B", "C"}
Dim Other(Items.Length - 1) As String
Items.CopyTo(Other, 0)
To more closely match you code above, but this will be less efficient
Dim Items(), Other() As String
