问题描述
Hello,
my datatable returns a row with several fields.
I can refer to all the field values except one of them which returns blank.
In immediate window it returns : dt.Rows[0]["Quarter"]
{}
Even if I refer to it by index number, it returns the same thing i.e. empty value
I can see in the stored proc it does return a value for field "Quarter"
Do you know what I am doing wrong?推荐答案
In immediate window it returns : dt.Rows[0]["Quarter"]
{}
表示dt.Rows [0] [Quarter]包含空值。
见表并查看值。
it means dt.Rows[0]["Quarter"] contains null value.
see in table and check the value.
