Cannot implicitly convert type 'string' to 'System.Windows.Forms.TextBox'

Question

I don't know what to do because the error is in the Form1.Designer.cs and because I have no experience in debugging that part of the program.

//Form1
// 
this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.ClientSize = new System.Drawing.Size(352, 246);
this.Controls.Add(this.groupBox2);
this.Controls.Add(this.groupBox1);
this.Font = new System.Drawing.Font("Tahoma", 8.25F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(0)));
this.Name = "Form1";
this.StartPosition = System.Windows.Forms.FormStartPosition.CenterScreen;
this.Text = "Generate Username";
this.groupBox1.ResumeLayout(false);
this.groupBox1.PerformLayout();
this.groupBox2.ResumeLayout(false);
this.groupBox2.PerformLayout();
this.ResumeLayout(false);

Answer 1

The error is on this.Name = "Form1";

I suspect you have created a control named Name , which conflicts with the Name property of the window. Just rename the control to something else and it should work again.

Answer 2

The error must come from somewhere else, there's nothing here with a TextBox . The error is probably caused by assigning a string to a TextBox itself instead of assigning a string to the Text property of the TextBox.

Example:

TextBox tb = new TextBox();
tb = "Default text";

This should be:

TextBox tb = new TextBox();
tb.Text = "Default text";

Otherwise you have created a control with a name like Name or Text , in which case you'll have to rename it to NameTextBox or something.
