Question

我需要管理'AccountText'变量，所以如果我传递一个带有特殊字符的值作为例如“MC＆amp; CO”，我不应该出错。

import math

# Define variables and create the grid
a = 0
b = 2
rounds = 5
# Size of the grid
y_max, x_max = 100, 100
# Center of the grid
origo_y, origo_x = 50, 50

# Every element in the grid is truly unique element
# If the grid is created like this
# Don't use for example [[" "]*x_max]*y_max
grid = [[" " for i in range(x_max)] for j in range(y_max)]

for angle in range(rounds*360):
    # Calculations for the spiral
    rads = math.radians(angle)
    r = a + b * rads
    y = r * math.sin(rads)
    x = r * math.cos(rads)
    x_coord = origo_x + round(x)
    y_coord = origo_y + round(y)

    if (0 <= x_coord < x_max) and (0 <= y_coord < y_max):
        grid[y_coord][x_coord] = "#"

# Print the whole grid
for line in grid:
    print("".join(line))

Answer 1

您可以在将AccountText包含在查询中之前对其进行编码：

AccountText = HttpUtility.HtmlEncode(AccountText);

据我所知，FetchXML使用XML的本机特殊字符处理，因此您可以将＆符号转义为&

例如：

<fetch version="1.0" output-format="xml-platform" mapping="logical" distinct="true" >
    <entity name="account" >
        <attribute name="accountid" />
        <filter type="and" >
            <condition attribute="name" operator="eq" value="MC&amp;Co" />
        </filter>
    </entity>
</fetch>

要为所有特殊字符执行此操作，有几种方法可以转义XML的字符串。最快的可能是使用System.Web库中的System.Security.SecurityElement.Escape（）方法：

string xml = "<node>it's my \"node\" & i like it<node>";
string encodedXml = System.Security.SecurityElement.Escape(xml);

输出： <node>it's my "node" & i like it<node>
