问题描述
当我做了LINQ包含撇号的场下选择我最近发现,它使我的应用程序抛出异常。
I recently found when I do a LINQ select under a field that contains an apostrophe, it makes my application to throw an exception.
DataRow[] newDr = this.ds.Tables["TableName"].Select("Name = '" + drData["Name"].ToString() + "'");
如果drData [名称] =该企业的钱
If drData["Name"] = "The business's money"
我得到的异常:
I got an exception of "Syntax error: Missing operand after 'S' operator "
谁能告诉我如何保护它,并没有更换或删除它,好吗?
推荐答案
您必须将单引号逃脱2单引号,有可能是其他特殊字符,所以你必须照顾他们:
You have to escape the single quote to 2 single quotes, there may be other special characters so you have to take care of them:
DataRow[] newDr = this.ds.Tables["TableName"]
.Select(string.Format("Name ='{0}'",drData["Name"].ToString().Replace("'","''")));
在过滤器中的字符串转义特殊字符(使用选择法):
