[!INCLUDEtsql-appliesto-ss2008-asdb-xxxx-xxx-md]

Write writes out a binary representation of SqlHierarchyId to the passed-in BinaryWriter. Write cannot be called by using [!INCLUDEtsql]. Use CAST or CONVERT instead.

void Write( BinaryWriter w )   

w
A BinaryWriter object to which the binary representation of this hierarchyid node will be written out.

CLR return type:void

Write is used internally by [!INCLUDEssNoVersion] when it is necessary, such as when loading data from a hierarchyid column. Write is also called internally when a conversion is done between hierarchyid and varbinary.

MemoryStream stream = new MemoryStream();  
BinaryWriter bw = new BinaryWriter(stream);  
hid.Write(bw);  
byte[] encoding = stream.ToArray();
