C# 如何处理Access SQL表达式中字符串变量的单引号或双引号

我用c#写这行代码是为了操作microsoft access数据库

OleDbCommand sComm = new OleDbCommand
  ("Update TableToBeImport set TextDefault = '" + resxValue + "' 
    WHERE ControlName = '" + resxKey + "'" , c);

resxValue

和

resxKey

都是字符串变量

当两个字符串变量很简单时，如“abc”、“xyz”，一切正常，但当一个字符串变量变得复杂时，在我的例子中，如下所示：

小贴士:

要修复费率计划和rpt错误，请使用“重新处理”

要修复运营商、中继组、交易员错误，请使用“删除并重新插入”

程序抛出错误，当我进行调试时，sComm.CommandText的格式如下：

更新TableToBeImport set TextDefault='提示：\r\n1。厘定差饷计划 &rpt错误使用“重新处理”\r\n2。要修复运营商、中继组、交易员错误， 使用“删除并重新插入”，其中ControlName='frmCDRQuery.label7.Text'

我知道在c#中，我可以在字符串变量之前使用

@

，因此其中的任何转义字符都将被忽略。但是在ACCESS中，我怎样才能得到相同的结果呢？

这对您有用吗

var resxValue = ""; // obviously this will be whatever the type and value that is required
var resxKey = ""; // obviously this will be whatever the type and value that is required

// I am assuming here that you are already programming with a `using` statement
using (OleDbConnection c = new OleDbConnection(""))
{
    using (OleDbCommand sComm = new OleDbCommand("UPDATE TableToBeImport SET TextDefault = @p0 WHERE ControlName = @p1", c))
    {
        sComm.Parameters.Add(new OleDbParameter("@p0", resxValue));
        sComm.Parameters.Add(new OleDbParameter("@p1", resxKey));

        // rest of your code here E.G., sComm.ExecuteNonQuery();
    }
}
