有点晚了，但我已经创建了一个web工具来帮助创建一个c#(或其他)对象从SQL结果，SQL表和SQL SP。

sql2object.com

这可以让你安全地输入所有的属性和类型。

如果无法识别类型，则将选择默认类型。

从顶部回复略有修改:

            ) pkk
where pkk.ColumnName = t.ColumnName
order by ColumnId

set @Result = @Result  + '
}'

print @Result

这使得输出需要完整的LINQ在c#声明

[System.Data.Linq.Mapping.Table(Name = "HistoricCommand")]
public class DboHistoricCommand
{
    [System.Data.Linq.Mapping.Column(Name = "HistoricCommandId", IsPrimaryKey = true)]
    public int HistoricCommandId { get; set; }

    [System.Data.Linq.Mapping.Column(Name = "PHCloudSoftwareInstanceId", IsPrimaryKey = true)]
    public int PHCloudSoftwareInstanceId { get; set; }

    [System.Data.Linq.Mapping.Column(Name = "CommandType", IsPrimaryKey = false)]
    public int CommandType { get; set; }

    [System.Data.Linq.Mapping.Column(Name = "InitiatedDateTime", IsPrimaryKey = false)]
    public DateTime InitiatedDateTime { get; set; }

    [System.Data.Linq.Mapping.Column(Name = "CompletedDateTime", IsPrimaryKey = false)]
    public DateTime CompletedDateTime { get; set; }

    [System.Data.Linq.Mapping.Column(Name = "WasSuccessful", IsPrimaryKey = false)]
    public bool WasSuccessful { get; set; }

    [System.Data.Linq.Mapping.Column(Name = "Message", IsPrimaryKey = false)]
    public string Message { get; set; }

    [System.Data.Linq.Mapping.Column(Name = "ResponseData", IsPrimaryKey = false)]
    public string ResponseData { get; set; }

    [System.Data.Linq.Mapping.Column(Name = "Message_orig", IsPrimaryKey = false)]
    public string Message_orig { get; set; }

    [System.Data.Linq.Mapping.Column(Name = "Message_XX", IsPrimaryKey = false)]
    public string Message_XX { get; set; }

}

我只是想给感兴趣的人加上我自己的答案。 主要特点有:

It will automatically generate classes for all the tables in the entire schema. Just specify the schema name. It will add System.Data.Linq.Mapping attributes to the class and each property.

我尝试使用上面的建议，并在这个过程中改进了这个线程中的解决方案。

我确实将类重命名为ObservableObject，并使用CallerMemberName属性利用了c# 5的一个特性

下面是你们会更喜欢的部分。我构建了一个Powershell脚本来为SQL数据库中的所有表生成。它是基于一个名为Chad Miller的Powershell大师的Invoke-SQLCmd2 cmdlet，可以从这里下载: http://gallery.technet.microsoft.com/ScriptCenter/7985b7ef-ed89-4dfd-b02a-433cc4e30894/

一旦有了cmdlet，为所有表生成的Powershell脚本就变得简单了(一定要用特定的值替换变量)。

. C:\MyScripts\Invoke-Sqlcmd2.ps1

$serverInstance = "MySQLInstance"
$databaseName = "MyDb"
$generatorSQLFile = "C:\MyScripts\ModelGen.sql" 
$tableListSQL = "SELECT name FROM $databaseName.sys.tables"
$outputFolder = "C:\MyScripts\Output\"
$namespace = "MyCompany.Business"

$placeHolderSchema = "&Schema"
$placeHolderTableName = "&TableName"
$placeHolderNamespace = "&Namespace"

#Get the list of tables in the database to generate c# models for
$tables = Invoke-Sqlcmd2 -ServerInstance $serverInstance -Database $databaseName -Query $tableListSQL -As DataRow -Verbose

foreach ($table in $tables)
{
    $table1 = $table[0]
    $outputFile = "$outputFolder\$table1.cs"


    #Replace variables with values (returns an array that we convert to a string to use as query)
    $generatorSQLFileWSubstitutions = (Get-Content $generatorSQLFile).
                                            Replace($placeHolderSchema,"dbo").
                                            Replace($placeHolderTableName, $table1).
                                            Replace($placeHolderNamespace, $namespace) | Out-String

    "Ouputing for $table1 to $outputFile"

    #The command generates .cs file content for model using "PRINT" statements which then gets written to verbose output (stream 4)
    # ...capture the verbose output and redirect to a file
    (Invoke-Sqlcmd2 -ServerInstance $serverInstance -Database $databaseName -Query $generatorSQLFileWSubstitutions -Verbose) 4> $outputFile

}

我将几个基于SQL的答案(主要是Alex Aza的根答案)打包到kassify中，这是一个控制台应用程序，可以一次性为指定的数据库生成所有类:

例如，给定一个Users表，它是这样的:

+----+------------------+-----------+---------------------+
| Id |       Name       | Username  |        Email        |
+----+------------------+-----------+---------------------+
|  1 | Leanne Graham    | Bret      | Sincere@april.biz   |
|  2 | Ervin Howell     | Antonette | Shanna@melissa.tv   |
|  3 | Clementine Bauch | Samantha  | Nathan@yesenia.net  |
+----+------------------+-----------+---------------------+

klassify将生成一个名为Users.cs的文件，看起来像这样:

    public class User 
    {
        public int Id {get; set; }
        public string Name { get;set; }
        public string Username { get; set; }
        public string Email { get; set; }
    }

它将为每个表输出一个文件。丢弃你不用的东西。

使用

 --out, -o:
        output directory     << defaults to the current directory >>
 --user, -u:
        sql server user id   << required >>
 --password, -p:
        sql server password  << required >>
 --server, -s:
        sql server           << defaults to localhost >>
 --database, -d:
        sql database         << required >>
 --timeout, -t:
        connection timeout   << defaults to 30 >>
 --help, -h:
        show help

我很困惑你想要从这里得到什么，但这里是在设计你想要设计的东西时的一般选择。

在Visual Studio版本中使用内置的ORM。 自己编写一个，类似于您的代码示例。通常情况下，如果你不确定怎么做，教程是你最好的朋友。 使用另一种ORM，如NHibernate。
