使用给定参数创建新的 SqlBinaryExpression 。

public Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlBinaryExpression MakeBinary (System.Linq.Expressions.ExpressionType operatorType, Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlExpression left, Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlExpression right, Microsoft.EntityFrameworkCore.Storage.RelationalTypeMapping typeMapping);
public Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlBinaryExpression? MakeBinary (System.Linq.Expressions.ExpressionType operatorType, Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlExpression left, Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlExpression right, Microsoft.EntityFrameworkCore.Storage.RelationalTypeMapping? typeMapping);
abstract member MakeBinary : System.Linq.Expressions.ExpressionType * Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlExpression * Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlExpression * Microsoft.EntityFrameworkCore.Storage.RelationalTypeMapping -> Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlBinaryExpression
Public Function MakeBinary (operatorType As ExpressionType, left As SqlExpression, right As SqlExpression, typeMapping As RelationalTypeMapping) As SqlBinaryExpression

参数

operatorType
ExpressionType

一个 ExpressionType 表示 SQL 一元运算符的 。

left
SqlExpression

二元运算的左操作数。

right
SqlExpression

二元运算的右操作数。

typeMapping
RelationalTypeMapping

要分配给创建的表达式的类型映射。

返回

SqlBinaryExpression

具有 SqlBinaryExpression 给定参数的 。
