在LINQtoSQL中搜索_Linq_Linq To Sql_Search_Where Clause

在LINQtoSQL中搜索

linq linq-to-sql search

在LINQtoSQL中搜索,linq,linq-to-sql,search,where-clause,Linq,Linq To Sql,Search,Where Clause,我有一些这样的代码： Function GetTypeFromTableName(ByVal _TableName As String, ByVal _DataContext As DataContext) Dim Mytype As Type = (From t In _DataContext.Mapping.GetTables Where t.TableName = "dbo." + _TableName Select t.RowType.Type).SingleOrDefault

我有一些这样的代码：

Function GetTypeFromTableName(ByVal _TableName As String, ByVal _DataContext As DataContext)

    Dim Mytype As Type = (From t In _DataContext.Mapping.GetTables Where t.TableName = "dbo." + _TableName Select t.RowType.Type).SingleOrDefault
    Return Mytype

End Function

Dim DBA As New LINQDataContext
_TBLName="City"
TableType = GetTypeFromTableName(_TBLName, DBA)

Dim GridQuery = From T In DBA.GetTable(TableType) Select T

If Chk.Checked Then
    CallByName(obj, "CName", CallType.Set, Txt_Name.Text)
    GridQuery = From T In DBA.GetTable(TableType) Where T Like obj
End If

此搜索不起作用，我收到以下错误：

{“方法”System.Object LikeObject（System.Object，系统对象,， Microsoft.VisualBasic.CompareMethod“ 没有支持到的翻译 SQL.}System.Exception

我应该为这个过滤器做什么？ vb.net linq

其中T.Contains（obj）
