이런 에러를 발견했다 -_-^ 이것때문에 하루종일 매달렸지만 원인은

non printing ascii code를 TextBox.Text 속성에 복사해서 붙여넣었기 때문이었다.
난 behind source쪽은 건드리지도 않았는데 계속 이런 에러를 받으니 속이 뒤집어지는 줄 알았다.

짧은 영어로나마 에러 피드백을 했다.

고쳐지면 좋겠는데 말이지..ㅎ

에러 발생 소스코드를 보자
behind 소스이다.

Form2.Designer.cs file

namespace WindowsFormsApplication1
{
    partial class Form2
    {
        /// 

        /// Required designer variable.
        /// 
        private System.ComponentModel.IContainer components = null;

        /// 

        /// Clean up any resources being used.
        /// 
        ///

        {

            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }

        #region Windows Form Designer generated code

        {
            this.textBox1 = new System.Windows.Forms.TextBox();
            this.SuspendLayout();
            // 
            // textBox1
            // 
            this.textBox1.Location = new System.Drawing.Point(12, 12);
            this.textBox1.Name = "textBox1";
            this.textBox1.Size = new System.Drawing.Size(100, 20);
            this.textBox1.TabIndex = 3;
            this.textBox1.Text = "12      "; //<--이것이 문제라는 말씀!!!
            // 
            // Form2
            // 
            this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
            this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
            this.ClientSize = new System.Drawing.Size(124, 50);
            this.Controls.Add(this.textBox1);
            this.Name = "Form2";
            this.Text = "Form2";
            this.ResumeLayout(false);
            this.PerformLayout();

        }

        #endregion

        private System.Windows.Forms.TextBox textBox1;
    }
}

문제의 아래 소스코드를 보자

this.textBox1.Text = "12      ";

위에서 눈에보이는
"12[공백][공백][공백]" 만 있는것이 아니라
"12[non printing ascii code][공백][공백][공백][non printing ascii code]"
이렇게 들어있단 말씀

이 값을 복사해서 넣으면 암만 error message를 읽어도 해결안되는 에러를 보게된다는 말씀!!
게다가 주석처리를 해도 에러는 여전히 생겼었다. -_-a
저 라인을 삭제하지 않는 이상 에러를 계속 보게 될 것이다. ㅠ
ㅠㅠ
