如何向WebMatrix Database.Query添加参数? [英] How to add parameters to WebMatrix Database.Query?

问题描述

使用Database.Query对我的代码的可读性进行了巨大的改进:

Using Database.Query has has made a huge improvement on readability in my code:

String Select = 'sp_getAllUsers';
WebMatrix.Data.Database DB = WebMatrix.Data.Database.Open(MyConString);
var data = DB.Query(Select);

我想切换到非存储过程查询. MSDN说查询方法的一个可选参数，Object[]，可以作为SQL参数传递，但是它们没有任何进一步的信息.

I'd like to switch to a non-stored procedure query. The MSDN says there's an optional parameter to the Query Method, Object[], that can be passed as SQL parameters, however they don't have any further information about it.

所以我有两个问题:

• 如何创建Object[]?
• 以这种方式添加参数是否可以防止诸如SQL注入之类的黑客威胁?

这是我尝试过的内容的简化版本:

Here's an abridged version of what I have tried:

Select = "Select * From Users Where first_name = "Foo" AND last_name = "Bar"

// Like Javascript
Object[] params = {"first_name" : "Foo"}, {"last_name" : "Bar"};

// More Like What I think it will be
Object[] Params = (String Name = "first_name", String First_Name = "Foo");

var data = DB.Query(Select, params);

我看过的所有资源似乎都引用了旧方法. 此已关闭，但他未使用查询的parameter参数方法.

All the sources I've looked at only seem to reference the old way. This is close, but he doesn't use the parameter parameter of the Query method.

推荐答案

尝试使用以下语法:

string selectCommand = "sp_getAllUsers(@0, @1)";
// selectCommand = "Select * From Users Where first_name = @0 AND last_name = @1";
...
var data = DB.Query(selectCommand, "Foo", "Bar");

此外，使用参数将始终阻止SQL注入，因为它总是将双引号引起来.

Also, using a Parameter will always prevent SQL Injection as it always double quote a single quote.
