Description Andrew Knowles 2014-06-12 17:38:49 UTC
There are several issues with SqlBulkCopy's varbinary support:
1) BulkCopyData (TdsBulkCopy.cs) does not send the appropriate size (1 byte instead of 2 bytes)
				else if (parameter.TypeName == "varbinary")
					tds.Comm.Append ((short) size);

2) GenerateColumnMetaData (SqlBulkCopy.cs) does not generate a size clause
				} else if (sqlType == SqlDbType.VarBinary && columnSize != -1) {
					columnInfo = string.Format ("{0}({1})",
3) BulkCopyToServer (SqlBulkCopy.cs) does not set the size parameter (it is set to parameter.size which is 0 instead of param.size)
Change from (2 places):
										size = parameter.Size;
to (2 places):
										size = param.Size;

Mono 5.10 has significantly improved System.Data implementation which should resolve this issue. If you can still reproduce it please reopen the issue.
