您要存储在字符串中的内容字符串?
您要存储sql查询或整个com对象...
如果您要存储整个com对象，那么
我认为这不可能

what u want to store in a string?
You want to store the sql query or entire com object...
If u r trying to store entire com object then
I think It is not possible

是的，不可能将cmd对象存储在字符串中.
如果您想查询，请使用它.

Yes it is not possible to store cmd object in string.
if you want to get query then use this.

string query=cmd.CommandText;

试试这个

Hi,

try this

string val=com.ExecuteScalar ().tostring();

在sql中执行后返回查询结果
***的

It returns the result of your query after executing in sql

All the Best
