Cannot Assign "AppendText" because it is a "method group".
public partial class Form1 : Form
{
String text = "";
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
String inches = textBox1.Text;
text = ConvertToFeet(inches) + ConvertToYards(inches);
textBox2.AppendText = text;
}
private String ConvertToFeet(String inches)
{
int feet = Convert.ToInt32(inches) / 12;
int leftoverInches = Convert.ToInt32(inches) % 12;
return (feet + " feet and " + leftoverInches + " inches." + " \n");
}
private String ConvertToYards(String inches)
{
int yards = Convert.ToInt32(inches) / 36;
int feet = (Convert.ToInt32(inches) - yards * 36) / 12;
int leftoverInches = Convert.ToInt32(inches) % 12;
return (yards + " yards and " + feet + " feet, and " + leftoverInches + " inches.");
}
}
The error is on the line "textBox2.AppendText = text", inside the button1_Click method.
Use following
textBox2.AppendText(text);
Instead of
textBox2.AppendText = text;
AppendText
is not a property but a method. Thus it needs to be invoked with parameter and cannot be assigned directly.
Properties are special methods, that support assignments due to special handling in compiler.
改为执行此操作(AppendText 是一种方法,而不是属性;这正是错误消息告诉您的内容):
textBox2.AppendText(text);
textBox2.AppendText(text);
is a method . You have to call it like one. You were performing an assignment operation on a method.
您必须以这种方式调用 AppendText:
textBox1.AppendText("Some text")
AppendText 是一种方法,您必须调用它。
textBox2.AppendText(text);
I figured out that the variable name declared was similar to a method name and hence it didn't allow me to assign a value.
The moment I changed the name it worked!
