Property Value
| Type | Description |
|---|---|
| ICollection<string> |
Methods

Parameters
| Type | Name | Description |
|---|---|---|
| string | columnName |
GetDataTypeName(string)

RewindReadIndex()
The IDataReader is iterated via the Read() method - once the last record was read, the Read() will return false. If you want to iterate again, you can use this method to "rewind" and start with the first record again.
Declaration
void RewindReadIndex()
