String.Replace Anomoly [英] String.Replace Anomoly

问题描述

通常，我对String.Replace（）没有任何问题。但是，我发现我需要更换角色的多个实例

a （\ xAAA）带有＃符号。输入文件是一行简单的

文件。我在文件中读入一个名为strLine的字符串。然后，当我用
做一个简单的替换...这是我尝试过的：


strLine = strLine.Replace（" a"，" ＃"）; //不替换......


strLine = strLine.Replace（@a，＃）; //不替换......


strLine = strLine.Replace（@" \ xAA"，"＃"）; //不能替换...


if（strLine.Contains（@" \ xAA"））MessageBox.Show（" found one"）; //否

消息框...


if（strLine.Contains（" a"））MessageBox.Show（" found one"） ; //没有消息

box ...

if（strLine.Contains（@" a"））MessageBox.Show（" found one" ）; //没有

留言框...


任何想法要么是我做错了，要么是更好的方法来尝试

替换是持久的角色，只是不会消失？

我认为你已经尝试了所有可能的组合，除了一个

有效...试试这个：


strLine = strLine.Replace（" \ xAA"，"＃"）;

看起来你的strLine有问题。


以下按预期工作


string test =" \ xAA a" ;;

MessageBox.Show（

String.Concat（test，Environment.NewLine，

test.Replace（" a"，"＃"），

Environment.NewLine ，

test.Replace（" \ xAA"，"＃"）））;

以下适用于我：


string feminineIndicatorChar = Char.ConvertFromUtf32（0xaa ）;

string b = feminineIndicatorChar.Replace（feminineIndicatorCha r，

"＃"）; // b =="＃"


你确定你的strLine确实包含女性序数

指标吗？你能检查调试器吗？

Normally, I never have any problems with String.Replace(). However, I
found that I need to replace multiple instances of the character
"a" (\xAA) with a # symbol. The input file is a simple one line
file. I read in the file into a string called strLine. Then when I
do a a simple replace ... here is what I have tried:

strLine = strLine.Replace("a", "#"); // Doesn''t replace ...

strLine = strLine.Replace(@"a", "#"); // Doesn''t replace ...

strLine = strLine.Replace(@"\xAA", "#"); // Doesn''t replace ...

if (strLine.Contains(@"\xAA")) MessageBox.Show("found one"); // No
message box ...

if (strLine.Contains("a")) MessageBox.Show("found one"); // No message
box ...

if (strLine.Contains(@"a")) MessageBox.Show("found one"); // No
message box ...

Any ideas either what I''m doing wrong, or a better way to try to
replace is persistent character that just won''t go away?

I think that you have tried every possible combination except the one
that works... Try this:

strLine = strLine.Replace("\xAA", "#");

Look like there is a problem with your strLine.

Following works as expected

string test = "\xAA a";
MessageBox.Show(
String.Concat(test,Environment.NewLine,
test.Replace("a", "#"),
Environment.NewLine,
test.Replace("\xAA", "#")));

The following works for me:

string feminineIndicatorChar = Char.ConvertFromUtf32(0xaa);
string b = feminineIndicatorChar.Replace(feminineIndicatorCha r,
"#"); // b == "#"

Are you sure your strLine really contains the feminine ordinal
indicator? Can you check in a debugger?
