Key: apple, Value: green Dictionary Item. Key: cherry, Value: red Dictionary Item. Key: banana, Value: yellow Enumerating dictionary keys Dictionary Key: apple Dictionary Key: cherry Dictionary Key: banana Enumerating dictionary values Dictionary Value: green Dictionary Value: red

If you select Start Without Debugging from the Visual Studio Debug menu, you will see that the Silverlight application appears in its own window, as shown in Figure 35-27.

This is the data declaration of the OddOrEven application: .field public static valuetype CharArray8 Format at FormatData .data FormatData = bytearray(25 64 00 00 00 00 00 00) .data FormatData = bytearray(25 64 00 00 00 00 00 00) defines a data segment labeled FormatData. This segment is 8 bytes long and has ASCII codes of the characters % (0x25) and d (0x64) in the first 2 bytes and zeros in the remaining 6 bytes. The segment is described as bytearray, which is the most ubiquitous way to describe data in ILAsm. The numbers within the parentheses represent the hexadecimal values of the bytes, without the 0x prefix. The byte values should be separated by spaces, and I recommend you always use the two-digit form, even if one digit would suffice (as in the case of 0, for example). It is fairly obvious you can represent literally any data as a bytearray. For example, instead of using the quoted string in the instruction ldstr "odd!", you could use a bytearray presentation of the string: ldstr bytearray(6F 00 64 00 64 00 21 00 00 00)

Visual Studio will now create two projects within the solution (Figure 16-3): 16.HelloAzure 16.WebRole

The relational operators are applied to two numeric values, on either side of the operator. Each of these operators returns a bool, indicating the relationship between the numeric types; the bool type is
