SqlExpressionFactory.And 方法

定义

命名空间:

Microsoft.EntityFrameworkCore.Query

程序集:

Microsoft.EntityFrameworkCore.Relational.dll

包:

Microsoft.EntityFrameworkCore.Relational v8.0.0

创建表示 SqlBinaryExpression 按位 AND 运算的 。

public virtual Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlBinaryExpression And (Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlExpression left, Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlExpression right, Microsoft.EntityFrameworkCore.Storage.RelationalTypeMapping? typeMapping = default);

abstract member And : Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlExpression * Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlExpression * Microsoft.EntityFrameworkCore.Storage.RelationalTypeMapping -> Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlBinaryExpression
override this.And : Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlExpression * Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlExpression * Microsoft.EntityFrameworkCore.Storage.RelationalTypeMapping -> Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlBinaryExpression

Public Overridable Function And (left As SqlExpression, right As SqlExpression, Optional typeMapping As RelationalTypeMapping = Nothing) As SqlBinaryExpression

参数

left

SqlExpression

左操作数。

right

SqlExpression

右操作数。

typeMapping

RelationalTypeMapping

要分配给创建的表达式的类型映射。

返回

SqlBinaryExpression

表示 SQL 按位 AND 运算的表达式。

实现

And(SqlExpression, SqlExpression, RelationalTypeMapping)
