如何将类参数插入SQL（nvarchar（50）字段）并在c＃中使用

Question

我会将cls1中的任何数据插入到SQL Server（Nvarchar(50)列）中。此处显示的代码是我项目中的示例

请帮帮我

由于

class Cls1
{
    public static string projectid;
    public static string projectname;
}

using (SqlCommand cmdInsert = con.CreateCommand())
{
    cmdInsert.CommandType = CommandType.Text;
    cmdInsert.CommandText = string.Format(@"INSERT INTO total(projectid)" +
                                           "values(@projectid)");

    cmdInsert.Parameters.AddWithValue("@projectid", (ClsPQR1. projectid));
}

您需要执行命令：

using (SqlCommand cmdInsert = con.CreateCommand())
{
    cmdInsert.CommandType = CommandType.Text;
    cmdInsert.CommandText = string.Format(@"INSERT INTO total(projectid)" +
                                           "values(@projectid)");

    cmdInsert.Parameters.AddWithValue("@projectid", (ClsPQR1. projectid));
    cmdInsert.ExecuteNonQuery();
}
