错误：错误 1 无法将类型“int”隐式转换为“bool” E:\Webshop\User\Create.aspx.cs 45 24 E:\Webshop\


------解决方案--------------------
if(sqltext.ExecuteNonQuery() == 0)
------解决方案--------------------
错误信息给的那么明显还找不到问题？行号都告诉你，我真服了
if(sqltext.ExecuteNonQuery())
这个sqltext.ExecuteNonQuery()方法返回的是int吧，C#的if只能判断bool，不能判断int。

 
------解决方案--------------------
if(sqltext.ExecuteNonQuery()) 改成 if(sqltext.ExecuteNonQuery()！=0)
------解决方案--------------------

探讨

if(sqltext.ExecuteNonQuery()) 改成 if(sqltext.ExecuteNonQuery()！=0)

------解决方案--------------------
int count = Convert.ToInt32(sqlselect.ExecuteScalar());
if(sqltext.ExecuteNonQuery())
你的这两句代码明显有冲突。sqlselect.ExecuteScalar()方法的返回值如果是bool值的话那么int count = Convert.ToInt32(sqlselect.ExecuteScalar());这句就会报错，如果是int行的话if(sqltext.ExecuteNonQuery())if条件句就会报错
