How to get the length of array means how much words in array?

For name fetching I used array for splitting variable, but when I put only first name then it gives error so I think first we get count of variable then match.
so please help me.

My code is:-

C#

String[] Spilted = Name.Split(new string[] { " " }, StringSplitOptions.RemoveEmptyEntries);
      
            String firstname = Spilted[0];
            String lastname = Spilted[1];


            SqlCommand cmd = new SqlCommand("Select PROFILE_ID,FIRST_NAME,PROFILE_REQUEST_STATUS from DSProfile.HDR_PROFILE  where FIRST_NAME='" + firstname + "' and LAST_NAME='" + lastname + "'  and PROFILE_REQUEST_STATUS='" + false + "'", con);
            // SqlCommand cmd = new SqlCommand("Select p.PROFILE_ID,g.FRIEND_ID,p.FIRST_NAME,g.ACCEPT_STATUS from DSProfile.HDR_PROFILE p,DSMailBox.HDR_GROUP g where p.FIRST_NAME='" + friendname + "' and p.PROFILE_ID=g.FRIEND_ID and ACCEPT_STATUS='" + false + "'", con);
            SqlDataAdapter sda = new SqlDataAdapter(cmd);
            DataSet ds = new DataSet();
            sda.Fill(ds);
            int cnt = ds.Tables[0].Rows.Count;
            DT = ds.Tables[0];
            GridView1.DataSource = ds;
            GridView1.DataBind();

Are you sure words are always space-separated? How about some punctuation?

Solution 1

Use the Length[^] property:

C#

if( Spilted.Length == 1)
{
    // Code for first name only.
}
else
if( Spilted.Length == 2)
{
    // Code for first and last name.
}

try this

C#

String Name = "first last";
        String[] Spilted = Name.Split(new string[] { " " }, StringSplitOptions.RemoveEmptyEntries);
        String firstName, lastName;
        if (Spilted.Length == 2)
        {
            firstName = Spilted[0];
            lastName = Spilted[1];
        }
        else if (Spilted.Length == 1)
            firstName = Spilted[0];

hi,

Try this also i think you want to count words in the whole string...

C#

int count = 0;
        string st = "this is your string including spaces and we are counting spaces count plus one is your words in the sentance ";
        foreach (char c in st.Trim())
        {
            if (char.IsSeparator(c))
            {
                count++;
            }
        }
        int totWords = count + 1;
        lblResult.Text = count.ToString();

i know it will helps you 100%
Thank you.
