string.Format()给出“输入字符串的格式不正确” [英] string.Format() giving "Input string is not in correct format"
问题描述
在这里我该怎么办?
string tmp = @"
if (UseImageFiles) {
vCalHeader += ""<td><img onmousedown='' src= '{0}cal_fastreverse.gif' width='13px' height='9' onmouseover='changeBorder(this, 0)' onmouseout='changeBorder(this, 1)' style='border:1px solid white'></td>\n""; //Year scroller (decrease 1 year)
calHeight += 22;
}";
string x = "xter";
tmp = string.Format(tmp, x);
我得到
输入字符串的格式不正确
Input string was not in correct format
当尝试更改 {0} $ c时$ c>。我正在C#和WinForms中执行此操作。

. I am doing this in C# and WinForms.
未处理格式异常
输入字符串的格式不正确
Format Exception was unhandled

我得到的疑难解答提示:
Troubleshoot tips I get:
制作确保您的方法参数格式正确。将字符串转换为datetime时,在将每个变量放入DateTime对象之前,先分析字符串以取出日期。
Make sure your method arguments are in right format. When converting a string to datetime, parse the string to take out the date before putting each variable into the DateTime object.
推荐答案
string.Format()
认为每个 {或}都是占位符的一部分(例如您已经使用的 {0} )。
string.Format()
considers each '{' or '}' to be part of a placeholder (like '{0}' you already use). You need to escape each literal occurrence by doubling it.
因此,在您的情况下,请执行以下操作:
So in your case do:
string tmp = @"
if (UseImageFiles) {{
...
}}";
