推荐答案

尝试类似的事情.

Try something like this.

var query = from r in this.dtContacts.AsEnumerable()
                        where r.Field<string>("Name") == searchname
                        select new{ Age=r["Age"],Address=r["Address"]};

另外，如果要基于在文本框中键入的字母进行搜索，请在LINQ的条件下尝试字符串的StartsWith属性.它应该起作用，请尝试这样做.

Also,if you want to search based on letter typed in textbox,try StartsWith property of string in where condition of LINQ.It should work,havent tried that.

如果使用的是LinqDataSource您可能会找到感兴趣的LinqDataSource.Where和LinqDataSource.WhereParameters.

If you are using a LinqDataSource you will probably find the LinqDataSource.Where and LinqDataSource.WhereParameters of interest.
