The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: UI. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes. |
The example changes the line terminator from its default value of "\r\n" or vbCrLf to "\r\n\r\n" or vbCrLf + vbCrLf. It then calls the WriteLine() and WriteLine(String) methods to display output to the console.
using namespace System; void main() { array<String^>^ lines = gcnew array<String^> { "This is the first line.", "This is the second line." }; // Output the lines using the default newline sequence. Console::WriteLine("With the default new line characters:"); Console::WriteLine(); for each (String^ line in lines) Console::WriteLine(line); Console::WriteLine(); // Redefine the newline characters to double space. Console::Out->NewLine = "\r\n\r\n"; // Output the lines using the new newline sequence. Console::WriteLine("With redefined new line characters:"); Console::WriteLine(); for each (String^ line in lines) Console::WriteLine(line); } // The example displays the following output: // With the default new line characters: // // This is the first line. // This is the second line. // // With redefined new line characters: // // // // This is the first line. // // This is the second line.
