将 LINQ 翻译成 sql 语句

问题描述

我想将 LINQ 表达式树转换为 SQL 语句，但我不想为此编写自己的代码.

I want to translate LINQ expression tree to SQL statement and I don't want to write my own code for this.

示例:

var query = from c in Customers
where c.Country == "UK" &&
      c.City == "London"
select c);

到

SELECT ... FROM Customers AS c WHERE c.Country = "UK" AND c.City = "London"

我知道DataContext.Log，但我想使用:

query.ToSqlStatementString()

推荐答案

CustomDataContext dc = new CustomDataContext();
IQueryable<Customer> query =
  from c in dc.Customer
  where c.Country == "UK"
  select c;
//
string command = dc.GetCommand(query).CommandText;
