In this STR 10 fields are there so I want to check in my new string is there 10 fields

Not very clear question. Do you want to validate pattern of comma separated sub-string? Or pattern of the STR itself ? What is the pattern?

Try:

C#

string STR="0004168858,AB0688120881,15,PLATE CLAMPING CO,KTL 16,CEQP,GI31,1111,DV1111,22222222";
string[] parts = STR.Split(',');

This will break each element into a separate string in the array

Based on your latest comment, you need to validate the count of substring separated by comma in the main string STR.

C#

STR.Split(',').Count()

Above code will give you the count of the substrings in the main string.
Now if you want to validate through some kind of validation control, then you can use ErrorProvider control for windows application. Look for more details of error provider at http://www.c-sharpcorner.com/UploadFile/scottlysle/UseErrorProvider03082007210138PM/UseErrorProvider.aspx[^]

Hope that helps.

To check that your new string have 10 feild or not just split the string and get count of array by its arr.lenght proprety.

First you need to split the string to arrays for the validation.

C#

string STR="0004168858,AB0688120881,15,PLATE CLAMPING CO,KTL 16,CEQP,GI31,1111,DV1111,22222222";

string[] strArrays = STR.Split(',');

Now you have list of values in the 'strArrays', and you can validate the fields using foreach (or) for loop iterations.

C#

foreach(string st in strArrays)
{
  st //your validation goes here;
}

OR

C#

for(int i=0;i<strarrays.count;i++)>
{
 strArrays[i] //your validation goes here;
}
