C# 将Datetime格式从sql转换为Date，并绑定到Gridview only日期

使用此代码时，输出的时间类似于

03/05/2016 00:00:00

，但当我在SQL中运行此查询时，它会显示正确的输出，如

2016-05-03

，如果使用

BoundFields

，则可以执行此操作

using (con = new SqlConnection(con_str))
{
    con.Open();
    string sql = "select mcfact as Factory, mcarea as Department, mcloc as Location, mcroom as Room, mcline as Line, cast (scanned as date) from tb_MachineRecord where mcidno='" + cmbmcidno.Text + "' ";
    da = new SqlDataAdapter(sql, con);
    DataSet ds = new DataSet();
    da.Fill(ds);
    GridView7.DataSource = ds;
    GridView7.DataBind();
    con.Close();
}

有关更多日期时间格式的信息，请参阅。如果使用

边界字段，则可以执行此操作

using (con = new SqlConnection(con_str))
{
    con.Open();
    string sql = "select mcfact as Factory, mcarea as Department, mcloc as Location, mcroom as Room, mcline as Line, cast (scanned as date) from tb_MachineRecord where mcidno='" + cmbmcidno.Text + "' ";
    da = new SqlDataAdapter(sql, con);
    DataSet ds = new DataSet();
    da.Fill(ds);
    GridView7.DataSource = ds;
    GridView7.DataBind();
    con.Close();
}

有关更多日期时间格式的信息，请参见

<ItemTemplate><%# Convert.ToDateTime(Eval("myDBdate")).ToShortDateString() %></ItemTemplate>

出生日期是日期时间类型列
我认为您应该使用

<ItemTemplate><%# Convert.ToDateTime(Eval("myDBdate")).ToShortDateString() %></ItemTemplate>

select name,CONVERT(VARCHAR(10),date_of_birth,120) from tbl_Login

出生日期是日期时间类型列
而不是ds，您可以使用datatable的dt对象
select name,CONVERT(VARCHAR(10),date_of_birth,120) from tbl_Login

例如：

using (con = new SqlConnection(con_str))
{
    con.Open();
    string sql = "select mcfact as Factory, mcarea as Department, mcloc as Location, mcroom as Room, mcline as Line, CONVERT(VARCHAR(10),scanned,120) from tb_MachineRecord where mcidno='" + cmbmcidno.Text + "' ";
    da = new SqlDataAdapter(sql, con);
    DataSet ds = new DataSet();
    da.Fill(ds);
    GridView7.DataSource = ds;
    GridView7.DataBind();
    con.Close();
}

可以使用datatable的dt对象代替ds
例如：

using (con = new SqlConnection(con_str))
{
    con.Open();
    string sql = "select mcfact as Factory, mcarea as Department, mcloc as Location, mcroom as Room, mcline as Line, CONVERT(VARCHAR(10),scanned,120) from tb_MachineRecord where mcidno='" + cmbmcidno.Text + "' ";
    da = new SqlDataAdapter(sql, con);
    DataSet ds = new DataSet();
    da.Fill(ds);
    GridView7.DataSource = ds;
    GridView7.DataBind();
    con.Close();
}
