哪里错了

Question

哪里报错啊？strDSQL,new SqlConnection(DataConfiguration.ConnectionString)
还可以这样写啊，有学一招，呵呵

Answer 1

你的deleteCommand 是字段还是局部变量？看你有return deleteCommand的返回值,应该是局部变量吧，哪你的deleteCommand 变量在哪定义的?

Answer 2

dsCommand = new SqlDataAdapter();
public bool DeleteCourseRate(cCourseRateData oCourseRateData)
{
if (dsCommand == null)
{
throw new System.Exception("数据适配器没有初始化");
}
dsCommand.DeleteCommand = GetDeleteCommand();
dsCommand.Update(oCourseRateData,cCourseRateData.TableName); if (oCourseRateData.HasErrors)
{
oCourseRateData.Tables[cCourseRateData.TableName].GetErrors()[0].ClearErrors();
return false;
}
else
{
oCourseRateData.AcceptChanges();
return true;
}
}谢谢
