本文介绍了一个名为SQLString.cs的类，用于将文本转换为适用于SQL语句的字符串，通过使用静态方法GetQuotedString实现文本转换。

SQLString.cs

 

 

using System;

namespace MyBBS.DataAccessHelper
{
 /// <summary>
 /// SQLString 的摘要说明。
 /// </summary>
 public class SqlStringFormat
 {
  /// <summary>
  /// 公有静态方法，将文本转换成适合在Sql语句里使用的字符串。
  /// </summary>
  /// <returns>转换后文本</returns> 
  public static String GetQuotedString(String pStr)
  {
   return ("'" + pStr.Replace("'","''") + "'");
  }
 }
}

vtkjs数据流的一般情况是 source——filter——mapper——actor——render——renderwindow 资源——筛选资源（数据处理，一个或多个输入，但只有一个输出） ——映射筛选后的资源——可视化映射筛选后的资源——render——renderwindow 首先引入对应api import vtkFullScreenRenderWindow from 'vtk.js/Sources/Rendering/Misc/FullScreenRenderWindow';
