C#里查找和替换代码 需不需要加什么控件

做的笔记本只差这个了

Answer 1

//---查找基本代码-------------------------
string Searchstr;
int index=-1, searchStart=0;
Searchstr="要查询的";
index=richTextBox1.Find(Searchstr,searchStart,RichTextBoxFinds.MatchCase);
if(index>=0)
{
richTextBox1.SelectionStart=index;
richTextBox1.SelectionLength=Searchstr.Length;
searchStart=index+1;
}

//---替换基本代码-------------------------
string Searchstr;
int index, searchStart=0;
Searchstr="要替换的";
while(true)
{
index=richTextBox1.Find(Searchstr,searchStart,RichTextBoxFinds.MatchCase);
if(index>=0)
{
richTextBox1.SelectionStart=index;
richTextBox1.SelectionLength=Searchstr.Length;
richTextBox1.SelectedText="要替换的";
searchStart=index+Searchstr.Length+1;
}
else
break;
}

差不多这个样子
