已知现有表T1
想快速获取cs类结构
/// <summary> /// T1 /// </summary> public class T1 { /// <summary> /// 主键 /// </summary> public int ID { get; set; } /// <summary> /// 姓名 /// </summary> public string NameLijhs { get; set; } }
通过运行下面的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, '无')) + ' /// </summary> public ' + ColumnType + NullableSign + ' ' + ColumnName + ' { get; set; } ' from ( SELECT replace(col.name, ' ', '_') ColumnName, column_id ColumnId, prop.value ColName, case typ.name when 'bigint' then 'long' when 'binary' then 'byte[]' when 'bit' then 'bool' when 'char' then 'string' when 'date' then 'DateTime' when 'datetime' then 'DateTime' when 'datetime2' then 'DateTime' when 'datetimeoffset' then 'DateTimeOffset' when 'decimal' then 'decimal' when 'float' then 'float' when 'image' then 'byte[]' when 'int' then 'int' when 'money' then 'decimal' when 'nchar' then 'char' when 'ntext' then 'string' when 'numeric' then 'decimal' when 'nvarchar' then 'string' when 'real' then 'double' when 'smalldatetime' then 'DateTime' when 'smallint' then 'short' when 'smallmoney' then 'decimal' when 'text' then 'string' when 'time' then 'TimeSpan' when 'timestamp' then 'DateTime' when 'tinyint' then 'byte' when 'uniqueidentifier' then 'Guid' when 'varbinary' then 'byte[]' when 'varchar' then 'string' 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 from sys.columns col join sys.types typ on 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) ) t --order by ColumnId set @Result = @Result + ' }' print @Result
效果如下:
完美,copy到项目里即可。
