[C#] find word after a word?

Hello ppl! How can I make my application find a word after a word? I have done this in VB.NET with this code:

Dim str As String = TextBox1.Text$.Replace(" ", vbNullString)
        TextBox1.Text = TextBox2.Text$.Substring(TextBox2.Text$.IndexOf(str) + Val(str.Length + 1)).Split(" ")(0)

But, when I use VB.NET to C# converter I get this code:

string str = textBox1.Text.Replace(" ", null);
            textBox1.Text == textBox2.Text.Substring(textBox2.Text.IndexOf(str) + Conversion.Val(str.Length + 1)).Split(" ")(0);

I get errors, such as 'Conversion' does not exist in the current context. Can anyone help?

What I have tried:

string str = textBox1.Text.Replace(" ", null);
            textBox1.Text == textBox2.Text.Substring(textBox2.Text.IndexOf(str) + Conversion.Val(str.Length + 1)).Split(" ")(0);

That's the fault of your VB code: why are you doing this at all:

Val(str.Length + 1)

Val converts a string to a number, so you take two numbers, add them together, convert them to a string, then convert them back to a number...

Try:

string str = textBox1.Text.Replace(" ", null);
textBox1.Text = textBox2.Text.Substring(textBox2.Text.IndexOf(str) + str.Length + 1).Split(" ")[0];

Hi,

Your c# code.

C#

string str = textBox1.Text.Replace(" ", null);
string[] aryDados  = textBox2.Text.Substring(textBox2.Text.IndexOf(str) + (str.Length + 1)).Split(' ');
textBox1.Text = aryDados[0];

You can do it like this:

string text = "one word right";
var after = text.Split(new string[] { "word" }, StringSplitOptions.None);
if (after.Length > 1)
{
    string right = after[1].Trim(' ');
    string firstWordAfter = right.IndexOf(" ") > -1
                 ? right.Substring(0, right.IndexOf(" "))
                 : right;
