以下是存储过程的源代码:

示例:存储过程名'1_Proc_admin_publish'
exec dbo.tools_CS_SPROC_Builder '1_Proc_admin_publish'
显示结果如下(C#源码):
try { SqlParameter[] paramsToStore = new SqlParameter[4]; paramsToStore[0] = new SqlParameter("@memberName", SqlDbType.VarChar); paramsToStore[0].Size=60; paramsToStore[0].Value = ; paramsToStore[1] = new SqlParameter("@type", SqlDbType.Int); paramsToStore[1].Value = ; paramsToStore[2] = new SqlParameter("@static", SqlDbType.Int); paramsToStore[2].Value = ; paramsToStore[3] = new SqlParameter("@returnType", SqlDbType.Int); paramsToStore[3].Value = ; SqlHelper.ExecuteNonQuery(conn.Connection, CommandType.StoredProcedure,"1_Proc_admin_publish", paramsToStore); } catch(Exception excp) { } finally { conn.Connection.Dispose(); conn.Connection.Close(); }上是“如何将存储过程自动转成C#源码”这篇文章的所有内容,感谢各位的阅读!希望分享的内容对大家有帮助,更多相关知识,欢迎关注创新互联行业资讯频道!
