已知現有表T1

想快速獲取cs類結構

/// <summary>
///  T1    
/// </summary>
public class T1
{
    /// <summary>
    /// 主鍵    
    /// </summary>
    public int ID { get; set; }

    /// <summary>
    /// 姓名    
    /// </summary>
    public string NameLijhs { get; set; }

}

通過執行下面的sql即可，先配置表名。

declare @TableName sysname = 'T1'
declare @Result varchar(max) = '
/// <summary>
///  ' +  @TableName +
    
'    
/// </summary>
public class ' + @TableName + '
{'

select @Result = @Result + '
    /// <summary>
    /// ' +  CONVERT(NVARCHAR(500), ISNULL(ColName, '無')) +
    
'    
    /// </summary>
    public ' + ColumnType + NullableSign + ' ' + ColumnName + ' { get; set; }
'

    SELECT
        replace(col.name, ' ', '_') ColumnName,
        column_id ColumnId,

            else 'UNKNOWN_' + typ.name
        end ColumnType,
        case
            when col.is_nullable = 1 and typ.name in ('bigint', 'bit', 'date', 'datetime', 'datetime2', 'datetimeoffset', 'decimal', 'float', 'int', 'money', 'numeric', 'real', 'smalldatetime', 'smallint', 'smallmoney', 'time', 'tinyint', 'uniqueidentifier')
            then '?'
            else ''
        end NullableSign

            col.system_type_id = typ.system_type_id AND col.user_type_id = typ.user_type_id
            LEFT JOIN sys.extended_properties prop ON col.object_id = prop.major_id AND col.column_id = prop.minor_id
    where object_id = object_id(@TableName)

--order by ColumnId

set @Result = @Result  + '

print @Result

效果如下：

完美，copy到專案裡即可。
