Supported by the XNA FrameworkBitBoolean. An unsigned numeric value that can be 0, 1, or null.
Supported by the XNA FrameworkCharString. A fixed-length stream of non-Unicode characters ranging between 1 and 8,000 characters.
Supported by the XNA FrameworkDateDate data ranging in value from January 1,1 AD through December 31, 9999 AD.
Supported by the XNA FrameworkDateTimeDateTime. Date and time data ranging in value from January 1, 1753 to December 31, 9999 to an accuracy of 3.33 milliseconds.
Supported by the XNA FrameworkDateTime2Date and time data. Date value range is from January 1,1 AD through December 31, 9999 AD. Time value range is 00:00:00 through 23:59:59.9999999 with an accuracy of 100 nanoseconds.
Supported by the XNA FrameworkDateTimeOffsetDate and time data with time zone awareness. Date value range is from January 1,1 AD through December 31, 9999 AD. Time value range is 00:00:00 through 23:59:59.9999999 with an accuracy of 100 nanoseconds. Time zone value range is -14:00 through +14:00.

Supported by the XNA FrameworkTimestampArray of type Byte. Automatically generated binary numbers, which are guaranteed to be unique within a database. timestamp is used typically as a mechanism for version-stamping table rows. The storage size is 8 bytes.
Supported by the XNA FrameworkTinyIntByte. An 8-bit unsigned integer.
Supported by the XNA FrameworkUdtA SQL Server user-defined type (UDT).
Supported by the XNA FrameworkUniqueIdentifierGuid. A globally unique identifier (or GUID).
Supported by the XNA FrameworkVarBinaryArray of type Byte. A variable-length stream of binary data ranging between 1 and 8,000 bytes. Implicit conversion fails if the byte array is greater than 8,000 bytes. Explicitly set the object when working with byte arrays larger than 8,000 bytes.
Supported by the XNA FrameworkVarCharString. A variable-length stream of non-Unicode characters ranging between 1 and 8,000 characters. Use VarChar when the database column is varchar(max).
Supported by the XNA FrameworkVariantObject. A special data type that can contain numeric, string, binary, or date data as well as the SQL Server values Empty and Null, which is assumed if no other type is declared.
Supported by the XNA FrameworkXmlAn XML value. Obtain the XML as a string using the GetValue method or Value property, or as an XmlReader by calling the CreateReader method.

When setting command parameters, the SqlDbType and DbType are linked. Therefore, setting the DbType changes the SqlDbType to a supporting SqlDbType.
