Parameters
- fileName
- Type: SystemString
The file to write the output to. - diskInputs
- Type: System.Collections.GenericIListRecordInput
The disk inputs. - memoryInputs
- Type: System.Collections.GenericIListRecordInput
The memory inputs. - maxDiskInputsPerPass
- Type: SystemInt32
The maximum number of disk inputs per merge pass. - comparer
- Type: System.Collections.GenericIComparerT
The IComparerT to use, or to use the default. Do not pass Default. - allowRecordReuse
- Type: SystemBoolean
