以下範例示範如何使用此 Max 方法回傳並顯示兩個變數中較大的變數：

string str = "{0}: The greater of {1,3} and {2,3} is {3}.";

byte     xByte1    = 1,    xByte2    = 51;

/*
This example produces the following results:

Display the greater of two values:

Byte   : The greater of   1 and  51 is 51.
Int16  : The greater of  -2 and  52 is 52.
Int32  : The greater of  -3 and  53 is 53.
Int64  : The greater of  -4 and  54 is 54.
Single : The greater of   5 and  55 is 55.
Double : The greater of   6 and  56 is 56.
Decimal: The greater of   7 and  57 is 57.

(The following types are not CLS-compliant.)
