Console color output and console output

Console color output and console output

I am probably used to the console program with black and white characters: Today I am posting the simplest method to output color text and background on the console!

Method 1:

1. Set the background color of the console;

2. Set the foreground color of the console;

3. Call the WriteLine (XXX) method to output the content.

4. Call ResetColor () to restore the Console

The following is a simple example:

Class Program

{

[MTAThread]

Static void Main (string [] args)
{

Console. BackgroundColor = ConsoleColor. Green;

Console. ForegroundColor = ConsoleColor. Red;
WriteLine ("test output green background Red Letter ");
Console. ResetColor ();
Console. BackgroundColor = Console. BackgroundColor;
Console. ForegroundColor = ConsoleColor. Blue;
WriteLine ("blue words for test output ");
Console. ResetColor ();

}

}

Method 2. Call Win32API:

[DllImport ("Kernel32.dll", SetLastError = true, CharSet = CharSet. Auto)]
Public static extern IntPtr GetStdHandle (UInt32 type); // get the handle
[DllImport ("Kernel32.dll", SetLastError = true, CharSet = CharSet. Auto)]
[Return: financialas (UnmanagedType. U1)]
Public static extern bool SetConsoleTextAttribute (IntPtr consoleHandle, ushort attributes); // you can specify attributes.

Const UInt32 STD_OUTPUT_HANDLE = unchecked (UInt32) (-11 ));

IntPtr consoleHandle = GetStdHandle (STD_OUTPUT_HANDLE );
String s = "Hello World! ";
For (int I = 0; I <s. Length; I ++)
{
SetConsoleTextAttribute (consoleHandle, (ushort) (I + 1 ));
Console. Write (s [I]);
}
Console. ReadLine ();
