    StringBuilder

    Hello all ... i have a StringBuilder question. Im wondering the best way
    to go about "clearing" a StringBuilder after is has aready been appended to.

    heres the deal ... i have a textBox that i regurgitate ASCII information onto
    from a StreamReader. This textBox is on a form, and on this form i have a
    "Clear" button that essentially clears the textBox ...

    Code:
    
    	StringBuilder buffer = new StringBuilder();
    
    
            private void buttonClear_Click(object sender, EventArgs e)
            {
                outputFileTextBox.Text = "";
            }
    So ... if i want to clear the StringBuilder's "buffer" that already has "x"
    amount of bytes "appened" to it, and clear the textBox at the same time ... would this
    be the worst/best way to do to do it ... or would there be a better way, other then
    allocating another builder for the next read?


    Code:
    
    	StringBuilder buffer = new StringBuilder();
    
    
            private void buttonClear_Click(object sender, EventArgs e)
            {
                outputFileTextBox.Text = "";
                buffer = new StringBuilder();
    
            }
    Any info would be great !

    Check the StringBuilder reference for a Clear() method, or check the documentation of the Length property to see if setting it truncates. If it does, setting it to 0 would erase the contents.
    All the buzzt!
