我试图运行以下查询,它接受某人的名字,并尝试将其插入SQL Server数据库表.

$name = "Ronnie O'Sullivan"

$dataSource = "127.0.0.1"
$database = "Danny"
$connectionString = "Server=$dataSource;Database=$database;Integrated Security=True;"

$connection = New-Object System.Data.SqlClient.SqlConnection
$connection.ConnectionString = $connectionString
$connection.Open()

$query = "INSERT INTO People(name) VALUES('$name')"

$command = $connection.CreateCommand()
$command.CommandText = $query
$command.ExecuteNonQuery()

$connection.Close()

我面临的问题是单引号导致我的查询出现问题.查询正在执行

INSERT INTO People(name) VALUES('Ronnie O'Sullivan')

这会导致SQL语法错误.

我的问题是如何转义我的$ name变量,以便它在SQL端呈现.

一种解决方案是在我的$ name变量上进行查找和替换,找到:'replace:''

$name.Replace("'", "''")

那里有更优雅的解决方案,还是我似乎无法找到的功能？

谢谢.

我试图circle body用图像精灵替换标准，但它没有显示图像。

var Engine = Matter.Engine,
  Render = Matter.Render,
  World = Matter.World,
  Bodies = Matter.Bodies,
  Body = Matter.Body,
  Constraint = Matter.Constraint,
  Vector = Matter.Vector,
  Events = Matter.Events,
  Mouse = Matter.Mouse,
  MouseConstraint = Matter.MouseConstraint;

// create an engine
var engine = Engine.create();

engine.world.gravity.y = 0; // gravity not needed in this app

// create a renderer
var render = Render.create({
  element: document.body,
  engine: engine
});

var ball_0 = Bodies.circle(100, 100, 11, {

我正在尝试验证PersonPaymentDetails模型中的sortCode字段,但我的视图无法验证StringLength(6).如果我提交长度为1的表单,则表示错误验证成功.

我在这里做了一些根本错误的事吗？

public class PersonController : Controller
