| CrossApply(DbExpression, Func<DbExpression,KeyValuePair<String,DbExpression>>) |
Creates a new DbApplyExpression that evaluates the given apply expression once for each element of a given input set, producing a collection of rows with corresponding input and apply columns. Rows for which apply evaluates to an empty set are not included. |
| CrossApply(DbExpressionBinding, DbExpressionBinding) |
Creates a new DbApplyExpression that evaluates the given apply expression once for each element of a given input set, producing a collection of rows with corresponding input and apply columns. Rows for which apply evaluates to an empty set are not included. |

Public Function CrossApply (source As DbExpression, apply As Func(Of DbExpression, KeyValuePair(Of String, DbExpression))) As DbApplyExpressionParameters
- source
- DbExpression
A DbExpression that specifies the input set.
- apply
- Func<DbExpression,KeyValuePair<String,DbExpression>>
A method that specifies the logic to evaluate once for each member of the input set.
Returns
