从C＃将十进制数存储到数据库中

Question

I am trying to store decimal numbers into a SQL Server database where column datatype is numeric(10,2) .

The data passed from textbox to database using parameterized procedure as below

cmd.Parameters.Add(new SqlParameter("@PP", SqlDbType.Decimal)).Value = decimal.Parse(TB_PP.Text);

My problem it that I can enter decimal number directly into database table and when read it from database to textbox I get an decimal number

But when storing it through textbox it save an integer so what should I use instead of SqlDbType.Decimal ?

Answer 1

尝试使用双精度而不是十进制：

double.Parse(TB_PP.Text);

Answer 2

Try defining your Parameter this way:

cmd.Parameters.Add(new SqlParameter("@PP", SqlDbType.Decimal) {
    Precision = 10, 
    Scale = 2 
 });

My experience is when the SQL data type is decimal(10,2) and not numeric , but give it a try.
