如何在带有C＃的T-SQL脚本中基于中文单词（下午/上午）转换数据格式（基于中文版本的SQL Server） [英] How To Convert Data Format with Chinese words (下午/上午) In T-SQL Script with C# (based on SQL Server with Chinese Version)

问题描述

我在C＃中使用 SqlCommand 有问题，我需要将 DateTime 格式插入SQL Server，如下所示代码

I have a problem with SqlCommand in C#, I need to insert DateTime format to SQL Server like as following code

例如

using (SqlConnection conn = new SqlConnection("Data Source=127.0.0.1;Initial Catalog=B2CCompareData;Persist Security Info=True;User ID=sa;Password=1111;MultipleActiveResultSets=True;Connection Timeout=600; Application Name=EntityFramework"))
{
    conn.Open();                    
    SqlCommand cmd = conn.CreateCommand();                   

    try
    {
        cmd.CommandText = "Insert into table1(indexid,createTime) values(1,Convert(datetime, '2016/1/20 下午 04:21:07', 121))";
        cmd.CommandType = CommandType.Text;
        cmd.Connection = conn;                   

        cmd.ExecuteNonQuery();                   
    }
    catch
    {
        throw;
    }
}

2016/1/20 **下午** 04:21:07 ==> 混合中文单词的日期时间

但不幸的是我收到错误消息：

But unfortunately I get an error message:

从字符
字符串转换日期和/或时间时转换失败。

Conversion failed when converting date and/or time from character string.

那么我该怎么做才能解决此问题？

So that what can I do to fix this problem?

PS：上午是 AM / 下午是 PM

希望这个例子可以帮助您解决问题

Hopefully, this example can help you to deal with your problem

例如
C＃

 DateTime dt = DateTime.Now;
 string str = dt.ToString("yyyy-MM-dd HH:mm:ss.000");

     using (SqlConnection conn = new SqlConnection("Data Source=127.0.0.1;Initial Catalog=**;Persist Security Info=True;User ID=**;Password=**;MultipleActiveResultSets=True;Connection Timeout=600; Application Name=EntityFramework"))
                {
                    conn.Open();
                    SqlCommand cmd = conn.CreateCommand();
                    try
                    {
                        SqlCommand cmd = new SqlCommand(string.Format("INSERT INTO aa(IndexID,ChangeTime) VALUES (1, Convert(datetime, '{0}', 121)))",str ));
                        cmd.Connection = conn;
                        cmd.ExecuteNonQuery();
                       
                    }
                    catch
                    {
                        throw;
                    }
    
                }
)
