提个序列化保存的问题！

[henryfan1]

现在遇到一个问题，我把一个对象序列化后转成string,
把string值给textbox(win).text，可是textbox什么值的没有。
想问下textbox.text会不会限制某些字符的。
Byte[] bytes = SerializeObject(pObj);
string objtxt= System.Text.Encoding.Default.GetString(bytes);
return objtxt;
我是通过以上代码把byte转成string的.

在Web的TextBox是可以的。

what is bytes.Length?

how did you serialize the object? if it is MemoryStream, did you set its Position property = 0 after you serialize the object? show your code?

[henryfan1]

Class1 cls = new Class1();
cl1.Name ="henry";
string str =HFSoft.Serialization.Serializable.SingleOjb.SerializeObjectToString(cl1);
this.textBox1.Text = str;
调试时str是有值的，但给了textbox后，textbox什么都没有显示出来。
从textbox获取text是空值来的。

直接序列化成string，然后通过string反回序化是没问题。
在WEB下的TextBox也不存在这情况。就是win下的textbox,RichTextBox都有这个问题。

[saucer]

maybe those characters are not displayable, what does the following say? (assume this is winform)

MessageBox.Show(this.textBox1.Text.Length);

[henryfan1]

public byte[] SerializeObject(object pObj)
{
if(pObj == null)
return null;
System.IO.MemoryStream _memory = new System.IO.MemoryStream();
BinaryFormatter formatter = new BinaryFormatter();
formatter.Serialize(_memory,pObj);
_memory.Position = 0;
byte[] read = new byte[_memory.Length];
_memory.Read(read,0,read.Length);
_memory.Close();
return read;


}

[henryfan1]

Class1 cls = new Class1();
cls.Name ="henry";
string str =HFSoft.Serialization.Serializable.SingleOjb.SerializeObjectToString(cls);
this.textBox1.Text = str;
MessageBox.Show(textBox1.Text.Length.ToString());
str是有值的，
show的值是0;

[henryfan1]

Class1 cls = new Class1();
cls.Name ="henry";
string str =HFSoft.Serialization.Serializable.SingleOjb.SerializeObjectToString(cls);
MessageBox.Show(str.Length.ToString()); value:163
this.textBox1.Text = str;
MessageBox.Show(textBox1.Text.Length.ToString());value:0

[saucer]

that sounds really weird, I don't have VS.NET at hand, so I cannot test it for you

and I assume

this.textBox1.SelectionStart = 0;
this.textBox1.SelectedText = str;

doesn't work either


what about

Byte[] bytes = SerializeObject(pObj);

this.textBox1.Text = Convert.ToBase64String(bytes);

??

[sprrav]

是很奇怪，str为底下，textBox1.Text = str;
但是，监视到textBox1.Text==“”
"\0\0\0\0\0\0\0\0\0\0\0\0\0\0System.Collections.Hashtable\a\0\0\0\nLoadFactor\aVersion\bComparerHashCodeProvider\bHashSizeKeysValues\0\0\0\v\bSystem.Collections.IComparer$System.Collections.IHashCodeProvider\b霶8?\0\0\0\n\n\v\0\0\0\t\0\0\0\t\0\0\0\0\0\0\0\0\0\b\b\0\0\0\0\0\0\0\0\0\0\0\0\bI Love U\v"

[henryfan1]

Convert.ToBase64String(bytes);
用这个可以解决问题了，谢谢：）
