有没有办法像这样过滤 C# DataView？

Question

I am writing some code for filtering data in BindingSource in c#.

In DataTable , I have one column and data is something like this,

coding is very good

I want to filter data from string after every empty space like my example,

var ss = "coding is      ery"; 
var s = ss.Split(" ".ToCharArray(), StringSplitOptions.RemoveEmptyEntries);

var filter = ColumnName + " like \'%" + s[0] + "%\' ";

        for (int i = 1; i < s.Length; i++)
        {
            filter = filter +  "AND " + ColumnName + " like \'%" + s[i] + "%\' ";
        }

BindingSource.Filter = filter;

The problem here is that I will get all the data ( coding is very good ). I don't want to get the data when word is not starting with the correct letter. Example,

coding is ery.

I want to be like

"coding very is" or "is very coding".

I want correct starting letters but position of word doesn't matter.

Does anybody have an idea how to do that?

You need to check it this way:

var filter = "(" + columnName
    + " like \'" + s[0] + "%\' "          // first word
    + " OR like \'% " + s[0] + "%\' )";   //in a sentence

for (int i = 1; i < s.Length; i++)
{
    filter += "AND " + "(" + columnName
    + " like \'" + s[i] + "%\' "          // first word
    + " OR like \'% " + s[i] + "%\' )";   //in a sentence
}
