Handling Large Object (LOB) Parameters in the CLR
Applies to: SQL Server
Use SqlBytes and SqlChars to pass large object (LOB) binary type (varbinary(max)) and LOB character type (nvarchar(max)) parameters, respectively. These types allow streaming the LOB values from the database to the common language runtime (CLR) routine, instead of copying the entire value into managed space. SqlBinary and SqlString should be used only for small binary and character string values.
