You did not even show the code which causes the error. What you show is not it.

Try this:

C#

public StringBuilder name
{
  get
  {
    return new StringBuilder(this.txtresname.Text);
  }

  set
  {
    this.txtresname.Text = value.ToString();
  }
}

Actually you can not convert it, since StringBuilder is not a scalar type.
You can create a stringbuilder instance that is initiated with your string. (MSDN[^])

C#

Stringbuilder sb = new StringBuilder(YourStringVariable)

Supposing that txtresname is the field you want to be a stringbuilder, see following:

C#

class myclass
{
    private StringBuilder txtresname = new StringBuilder();

    public string name
       {
           get
           {
               return this.txtresname.ToString();
           }

           set
           {
               this.txtresname.Clear;
               this.txtresname.Append(value);
           }
       }
}

Please see my comment to the question. Of course one will not "convert" to another. How about just reading MSDN on the two classes? There two classes are related in the following way:

C#

string someString = //...
System.Text.StringBuilder stringBuilder = new System.Text.StringBuilder(someString);

//...

string resultOfBuild = stringBuilder.ToString(); //isn't this obvious? :-)

As to the references, this one would be the most useful:
Microsoft Q209354. :-)

Good luck,
